If a current flowing through a lightbulb is 10 ampere and the voltage difference across the lightbulb is 120 volts, how much resistance does the light bulb have?

Hint: Use your triangle!

• 1200 Ohm's

• 12 Ohm's

• 0.083 Ohm's

• 12 Amperes

Greater voltage results in more current.

• True

• False

Electric current can flow through a circuit only if it forms a closed loop.

• False

• True

All electric circuits must have at least four parts.

• True

• False
