How much power is produced if a voltage of #3 V# is applied to a circuit with a resistance of #2 Omega#?

Solve for I from the first equation and your values. Then use that value in the second equation to find the power.
V = IR and P = VI where P = Power in Watts, I = current in Amperes, and V = voltage in Volts, and R = resistance in Ohms.
