static electricity and friction
The rate of doing work is called POWER.
Power is also defined as the rate of transfer of energy. It measures the speed of how work is done.
The unit of power is WATT.
Power is computed by dividing WORK DONE by TIME TAKEN.
P = W/t
1 watt:
*power of a machine
*power of an agent that does work at the rate of 1 joule per secon
1000 watt = 1 kilowatt
1000 kilowatt = 1 megawatt
Answer with Explanation:
Electric field:It is the force per unit charge experienced by rest charge at any given point.
It is the area around the charge which is placed at rest.It is represented by E.
Mathematical formula:

Magnetic field:It is an area around moving charge in which moving charge particle experienced magnetic force in that area.
Magnetic field is represented by B.
Mathematical formula :

Where B=Magnetic field
q=Charge on particle
v=Velocity of particle
F=Magnetic force exert on particle
Answer :
The answer is clearly C
Explanation:
Because the only way currents move are to the side
