Maintenance Electrical and Robotics Systems

when the circuit is _____, current does not flow.

• open 
• closed

materials that allow electricity to flow through them are called

• conductors
• current
• fuse
• resistor

What is the current of a series circuit with a total resistance of 10 ohms and a voltage of 110 V

• 0.09

• 11.0

• 1100.0

• 10.0

What is the total resistance of the circuit shown above?

Which of the following would happen if you were to add additional voltage to a circuit? Check all that apply.

• The voltage would increase

• The current would increase

• The resistance would increase

• The bulbs would become brighter

If the current through the battery was 10A in this diagram. What would the current through each identical bulb be?

• 10A
• 5A
• 20A
• 0A

The voltage dropped across the 300 ohm resistor is

(Hint: Find equivalent resistance, use Ohm's Law to solve for total current, then use Ohm's Law to solve for voltage drop at the 300 ohm resistor)

• 6 V

• 9 V

• 2 V

• 30 V

Two resistors are connected in series. How is the total resistance calculated?

• R1 + R2

• R1 x R2

• (R1 x R2) / (R1 + R2)

• (R1 +R2) / (R1 x R2)

What happens to the current as more resistors are added to the circuit?

• • It increases

• • It decreases

• • It fluctuates randomly

• • It remains the same

Switch that stops the flow of electrical current when a circuit is overloaded.

• Fuse

• Circuit Breaker

• Open Circuit
