21.

A series circuit consists of three resistors. Two resistors are 1.2 k each. The total resistance is 12 k. The value of the third resistor

 A. is 9,600 B. is 960 C. is 1.2 k D. cannot be determined

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

22.

Four equal-value resistors are in series with a 12 V battery and 13.63 mA are measured. The value of each resistor is

 A. 22 B. 220 C. 880 D. 88

Explanation:

Total Resistance, r = 12 / 13.63

= 0.880 in ohms

Total Resistance, r= 880

Each resistance value = r/4

= 880/4

Each resistance value = 220 ohms.
