2. 

A string of five series resistors is connected across a 6 V battery. Zero voltage is measured across all resistors except R3. The voltage across R3 is

A. 0 V
B. 1.2 V
C. 6 V
D. 0.6 V

Answer: Option C

Explanation:

No answer description available for this question. Let us discuss.

3. 

A series circuit consists of three resistors with values of 120 , 270 , and 330 . The total resistance is

A. less than 120
B. the average of the values
C. 720
D. 120

Answer: Option C

Explanation:

No answer description available for this question. Let us discuss.

4. 

A certain series circuit consists of a 1/8 W resistor, a 1/4 W resistor, and a 1/2 W resistor. The total resistance is 1200 . If each resistor is operating in the circuit at its maximum power dissipation, total current flow is

A. 27 mA
B. 2.7 mA
C. 19 mA
D. 190 mA

Answer: Option A

Explanation:

Total P = P1 + P2 + P3 = 7/8w.

P = I2R.

I = sqrt (P/R)

Now, P = 7/8w, R = 1200 ohm.

Therefore,

I= sqrt ( (7/8)/1200 ) = 0.0270030862 = 27 mA.


5. 

Which of the following series combinations dissipates the most power when connected across a 120 V source?

A. one 220 resistor
B. two 220 resistors
C. three 220 resistors
D. four 220 resistors

Answer: Option A

Explanation:
