What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

• 25 V
• 10 V
• 2.5 V
• 0.4 V

Current times Resistance equals

• Power

• Voltage

• Amperage

• Ohm

Voltage divided by Resistance

• Current

• Power

• Ohms

• Watts

Voltage divided by Current

• Current

• Power

• Resistance

• Watts

If the Voltage is increased and the resistance stays the same, Current will

• Increase
• Decrease
• Stay the same
• X

If the Voltage stays the same and Resistance is increased, Current will 

• Increase
• Decrease
• Stay the same
• X

If the battery produced 12.6 Volts what would be the current flow for a 6 Ohm resistor?
