4/27 P

Which resistors should be combined first to simplify this circuit?

• R1

• R2

• R3

• None of the above

The combined resistance of R2 and R3 will be

• 1/4 Ω

• 2Ω

• 4 Ω

• 1 Ω

Using the simplified circuit, the total resistance will be

• 2 Ω

• 1/2 Ω

• 8 Ω

• 1/8 Ω

The voltage drop across R1 is 12 V. What is the voltage drop over R2 and R3 combined?

• 3 V

• 12 V

• 1 V

• 48 V

If the total voltage drop across R23 is 12 V, what must be the current going through R2 and R3?

• 1/3 A

• 48 A

• 3 A

• 4 A

If we calculated the current going through R2 to be 3 A, how much is the voltage drop across R2?

• 1/3 V

• 3 V

• 24 V

• 6 V

If we calculated the current going through R2 to be 3 A, how much is the voltage drop across R3?

• 1/3 V

• 3 V

• 24 V

• 6 V

The total current must equal the current going through R1 plus the current going through R23.

• True

• False
