• long circuit

• parallel circuit

• series circuit

What is the term for a reusable safety switch that breaks the circuit when the current gets too high?

• third prong

• fuse

• circuit breaker

• short circuit

• grounded

Find the voltage across R₁

• 12 V

What is the voltage needed to run a 9.2 ohm toaster on a 5.5 amps?

• 9.2 V

• 5.06 V

• 34.14 V

What happens to the current in a circuit as the resistance decreases?

• Current increases

• Current Decreases

• Current remains the same
