Current and power relationship
WebP = V * I. P = Power (watts) V = voltage (volts) I = current (amps) Looking back at our example of water flowing through a hose, we can now see how power is directly related to current and voltage using this equation. For example, imagine that you’re spraying the hose to turn a water wheel. The faster the wheel turns, the more power is generated. 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.
