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

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

Answer: Option B

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.
