WebbLearn the Power Formula. We’ve seen the formula for determining the power in an electric circuit: by multiplying the voltage in “volts” by the current in “amps” we arrive at an answer in “watts.” Let’s apply this to a circuit example: How to Use Ohm’s Law to Determine Current. In the above circuit, we know we have a battery voltage of 18 volts and a lamp … WebbFor the circuit shown below find the Voltage (V), the Current (I), the Resistance (R) and the Power (P). Voltage [ V = I x R ] = 2 x 12Ω = 24V Current [ I = V ÷ R ] = 24 ÷ 12Ω = 2A Resistance [ R = V ÷ I ] = 24 ÷ 2 = 12 Ω Power [ P = V x I ] = 24 x 2 = 48W Power within an electrical circuit is only present when BOTH voltage and current are present. Webb5 juni 2015 · For a simple circuit with a battery supplying a voltage V to a capacitor, let us assume that the charge on the capacitor is Q.
