Four equal-value resistors are in series with a 12 V battery and 13.63 mA are measured. The value of each resistor is
Options
A. 22 Ω
B. 220 Ω
C. 880 Ω
D. 88 Ω
Correct Answer
220 Ω
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.
