A)1/100 ohm.
B)1/4 ohm.
C)4 ohms.
D)100 ohms.

Question

Quizplus · Accepted Answer

According to Ohm's Law, resistance (R) is equal to the ratio of potential difference (V) to current (I), i.e., R = V/I. 
Here, V = 20 volts and I = 5 amperes. 
Therefore, R = 20/5 = 4 ohms. 
Hence, the correct option is C) 4 ohms.
