Why electric field lines are continuous? Electric field lines are continuous because they are imaginary lines or you can call it the locus of a curve. We know electric filed is a vector. And the imaginary filed lines are drawn in a certain way such that when we draw tangent at any point on the curve, then it will give the direction of electric field.
Why is electric field continuous? (a) An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other. … Hence, two field lines never cross each other.
Are electric field lines always continuous? Option A-No, the electric field is not always continuous. … Note- The electric field because of any charge will be continuous, if there is no other charge in the medium. It will be discontinuous if there is a charge at that viable point.
Why electric field lines are continuous and open loop? If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. … Therefore, we say electrostatic field lines never form closed loops.

Is coal efficient for generating electricity?
Typical thermal efficiency for utility-scale electrical generators is around 37% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.)
Why is ground type immune to electric type?
Lightning strikes birds and planes very easily because of their altitude. Ground is the lowest thing, so it’s rarely hit directly by lightning (it usually hits trees or buildings or utility poles), and when lightning hits the ground it doesn’t do anything to the ground.
