Extra Current and Power Calculations Practice Once again!!!
Current Calculation #1 • What is the current flowing through a circuit that has a voltage of 100.0 volts and a resistance of 15.0 ohms? I = V R I = 6.7 amps I = 100.0 volts 15.0 ohms
Current Calculations #2 • What is the current of a stove with a voltage of 22.0 volts and a resistance of 5.0 ohms? I = V R I = 4.4 amps I = 22.0 volts 5.0 ohms
Current Calculations #3 • What is the current of a circuit with a voltage of 12.0 volts and a resistance of 10.0 ohms? I = V R I = 1.2 amps I = 12.0 volts 10.0 ohms
Current Calculation #4 • What is the current of a circuit with a voltage of 80.0 volts and a resistance of 30.0 ohms? I = V R I = 2.7 amps I = 80.0 volts 30.0 ohms
Power Calculation #1 • A stereo uses 0.5 amps from a source of 115.0 volts. How much power is used by the stereo? P = V x I P = 115.0 volts x 0.5 amps P = 57.5 Watts
Power Calculation #2 • 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
Power Calculation #3 • A 1.5-volt battery produces a current of 0.2 amps. What is the power in the circuit? P = V x I P = 1.5 volts x 0.2 amps P = 0.3 Watts
Power Calculation #4 • A 15-volt battery produces a current of 0.225 amps. What is the power in the circuit? P = V x I P = 15.0 volts x 0.225 amps P = 3.375 Watts
