• Question 93:

  A circuit contains three parallel resistors. Each resistor has 3 amps flowing through them.

  What is the total current flowing through the circuit?

  A. 1 A

  B. 3 A

  C. 9 A

  D. 1.5 A

  Correct Answer: C

  For resistors in parallel, the total current is equal to the sum of the currents through each resistor.

• Question 94:

  Using a fuse rated higher than the required current rating of a circuit can __________.

  A. protect your circuit better

  B. cause the fuse to blow more often

  C. lower your power usage for that circuit

  D. result in serious damage to your circuit

  Correct Answer: D

  Using a higher rated fuse is dangerous and can result in serious damage to your circuit.

• Question 95:

  What is the total resistance when two 10 ohm resistors are connected in series?

  A. 5 ohms

  B. 10 ohms

  C. 20 ohms

  D. 100 ohms

  Correct Answer: C

  When resistors are in series, you simply add their resistance together to find a total resistance. 10 + 10 = 20 ohms.

• Question 96:

  Resistance is measured in __________.

  A. Watts

  B. Volts

  C. Ohms

  D. Farads

  Correct Answer: C

  Resistance is measure in ohms.

• Question 97:
