Current and charge relation
WebThe relationship between power, current and electric potential difference can be derived by combining the mathematical definitions of power, electric potential difference and current. Power is the rate at which energy is added to or removed from a circuit by a battery or a load. Current is the rate at which charge moves past a point on a circuit. WebJul 12, 2016 · I've come across the equation VI = Tw (voltage times current is equal to torque times angular velocity); because power in (voltage and current) is equal to power out (torque and angular velocity).This equation can be changed to T = (V*I)/w. This shows me that an increase in current AND voltage would create an increase in torque; and that …
