How many volts does a fresh 9v alkaline battery show? Only 9V alkaline batteries have a voltage that is exactly 9 volts. In the case of rechargeable batteries, the voltage may come even lower or higher than this range. This depends on the 9V cell chemistry.
How many volts should a new 9V battery have? A nine volt battery has six cells, so a new would have an open circuit voltage of 9.48V. A reading of 9V indicates a battery with no to less than 10% discharge. FWIW they do self discharge at about 2% a year.
Can you power a light with a battery? You don’t need electrical wires to power a light bulb. You can use a battery! Just like a flashlight runs on batteries, you can connect a battery to a small light fixture or bulb to light it up.
Can we light a bulb with battery and wire? Light the bulb using two wires. Attach one wire to the negative end of the battery and wrap the other end of the same wire around the base of the bulb. Attach the other wire to the positive end of the battery with electrical tape and to the base of the bulb, completing the circuit and lighting the bulb.

How to get 240 volts in house?
The way you get a 240-volt circuit is simple. A “double-pole” circuit breaker is clipped into both 120 buses at the same time, so the voltage to the circuit is doubled. That’s why 240-volt circuits need two hot wires and a neutral to carry the electricity to the appliance, plus a ground wire.
