What is the difference between batteries and generators in terms of energy conversion?
What is the difference between batteries and generators in terms of energy conversion?
Batteries convert chemical energy into electrical energy, while generators convert mechanical energy into electrical energy.
Define direct current and alternating current in terms of charge movement.
Define direct current and alternating current in terms of charge movement.
In direct current, charges move in a single direction. In alternating current, the direction of charge movement continually alternates.
What is electric power and how is it calculated?
What is electric power and how is it calculated?
Electric power is the rate of conversion of electrical energy, and it is calculated as P = I∆V or electric power = current  potential difference.
