Which of the following materials is the poorest electrical conductor? Nichrome is made of nickel, chromium, and iron. It has a resistivity of about 100×10−8 Ω·m. That’s a very high resistivity compared to the other metals, so it is the worst conductor: A is correct.
Which of the following is the poorest electrical conductor? Among the metals given above, Tungsten evidently has the highest resistance and therefore is the poorest conductor of electricity.
Which one of the following materials is the poorest material in conductivity? EXPLANATION: From the given options, Silver has the highest electrical conductivity, and Aluminum has the least. On a scale of 0 to 100 for electrical conductivity, silver ranks 100, with copper at 97 and gold at 76, aluminum at 60.
Which material is not good conductor? Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies. Cables are wires covered in plastic so we can handle them safely.
Which of the following materials is the poorest electrical conductor? – Related Questions
Why is toyota not making electric cars?
A top Toyota executive had reportedly told the news agency that the company does not want to be seen as an electric vehicle maker, but wants to be viewed as a carbon-neutral business instead. Toyota is aiming for carbon-neutrality at manufacturing plants by 2035, Toyoda said at Tuesday’s briefing.
How to find out where electric is in wall?
There are two kinds of stud finders that can help you find wires in a wall – magnetic and electric. A magnetic stud finder is used to detect metal nails in wall studs. Electronic stud finders produce a tiny electrical field that changes when the finder reaches a denser region in a wall.
Why copper conducts electricity?
Each copper atom has lost one electron and become a positive ion. … The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity.
How long to smoke a meatloaf in an electric smoker?
Place the meatloaf in the smoker, and smoke at 275°F (135°C) for 2 hours. After two hours, generously apply the remaining ⅓ cup of BBQ sauce over the top of the meatloaf. Continue to smoke for another hour or until the meatloaf reaches 160°F (72°C). Serve!

What electrical plug indonesia?
For Indonesia there are two associated plug types, C and F. Plug type C is the plug which has two round pins and plug type F is the plug which has two round pins, with two earth clips on the side. Indonesia operates on a 230V supply voltage and 50Hz.
How has electricity impacted our lives?
Electricity has many uses in our day to day life. It is used for lighting rooms, working fans and domestic appliances like using electric stoves, A/C and more. … Electricity also provides means of amusement, radio, television and cinema, which are the most popular forms of entertainment are the result of electricity.
What device is used to measure electrical current?
The electric current in one part of a circuit is measured with an ammeter, which gives a reading in ampere. To take the measurement, a gap is made in the circuit and the ammeter is connected into that gap, so that the charged particles moving around the circuit must pass through the meter.
When to do electrical cardioversion?
This procedure is used when the heart is beating very fast or irregular. This is called an arrhythmia. Arrhythmias can cause problems such as fainting, stroke, heart attack, and even sudden cardiac death. With electrical cardioversion, a high-energy shock is sent to the heart to reset a normal rhythm.
How much is electricity bill in grenada?
Grenada’s current average residential electricity price at EC$0.63/kWh is on par with other Caribbean islands. On a much larger scale, with a population more than 10 times greater than Grenada, the U.S. Hawaiian Islands’ residential rates are EC$0.80-EC$0.95/kWh.
How much power does an electric furnace use?
Electric furnaces range from 10 kilowatts to 50 kilowatts, we estimate that a 2,400 square foot home using a modern high efficiency electric furnace uses 18,000 watts for heating when the furnace is being used.
Why table salt does not conduct electricity?
Salts consist of ions: charged particles. In the solid state however, the ions are trapped in a lattice by electrostatic forces. This means that the charged particles cannot move around freely and therefore salts do not conduct electrivity in their solid state.
How often should fixed electrical installations be tested?
Most standard workplace environments need an Electrical Installation Condition Report to be produced at least every 5 years. However, there should be regular routine inspections conducted at least annually.
How can you heat a car without electricity?
Fortunately, there are a few other budget-friendly ways to keep warm until you can take your vehicle in for heater repair.
Why did graphene conduct electricity?
The high electrical conductivity of graphene is due to zero-overlap semimetal with electron and holes as charge carriers. … These free electrons present above and below the graphene sheet are called pi (π) electrons and enhance the carbon-to-carbon bonds.
Why are electricity prices too low?
Some cause prices to be too low–such as pollution externalities–while others cause prices to be too high–such as recovery of fixed costs. … Furthermore, we find that for most utilities the largest source of difference between price and SMC is the failure of price to reflect variation in SMC over time.
Is crude oil used to make electricity?
How is it made into electricity? The oil is burned to heat water and produce steam. This steam propels the blades of a turbine. This is attached to a generator, which produces electricity.
How do you know electric bill is correct?
There are several steps that can determine if the bill is accurate: First, check the reading on your meter and compare it to the ending reading on the recent bill. The reading on the meter should be higher than the reading on the current bill.
Why do i feel static electricity?
That tiny shock you feel is a result of the quick movement of these electrons. You can think of a shock as a river of millions of electrons flying through the air. … Static electricity happens more often during the colder seasons because the air is drier, and it’s easier to build up electrons on the skin’s surface.
When finding the net electric field at point p?
So, in order to find the net electric field at point P , we will have to analyze the electric field produced by each charge and how they interact (cancel or add together). We can draw a diagram of the situation, keeping in mind that positive charges create electric fields with vectors that point away from them.
