Current and Power Calculations Practice Math once again!!!

Current Calculation #1 What is the current flowing through a circuit that has a voltage of 10.0 volts and a resistance of 2.0 ohms? I = V R I = 10.0 volts 2.0 ohms I = 5.0 amps (A)

Current Calculations #2 What is the current of a stove with a voltage of volts and a resistance of 25.0 ohms? I = V R I = volts 25.0 ohms 25.0 ohms I = 8.8 amps (A)

Power Calculation #1 A stereo uses 5.0 amps from a source of volts. How much power is used by the stereo? P = V x I P = volts x 5.0 amps P = Watts

Power Calculation #2 A 9-volt battery produces a current of 0.5 amps. What is the power in the circuit?A 9-volt battery produces a current of 0.5 amps. What is the power in the circuit? P = V x I P = 9.0 volts x 0.5 amps P = 4.5 Watts
