Voltage, Current , and Resistance

How many Volts would it take to push 1 Amp through a resistance of 1 Ohm?

V = I(R)

• 10 volts
• 1 volt
• 48 volts
• 5 volts

If the current through a circuit is 2 A and the resistance of a light bulb in the circuit is 10 Ohms, what is the voltage difference across the light bulb?

V = I(R)
