ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Given
Resistance R = 15 ohms
Potential Difference V = 60 V
Current I = ?
According to the Ohm’s Law 
I = V/R = 60/15 = 4A
I = 4A

SSC JE Electrical 2018 with solution SET-1
 Determine the value of current (in A) through both the resistors of the given circuit.

−2, 1.5
2, 1.5
−2, −1.5
2, −1.5

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

 
Current through the 10Ω resistance
I1 = V/R = 20/10 = 2A
I1 = 2A
Now current through the 20Ω resistance
I2 = V − (-10)/R = (20 + 10)/20 = 1.5 A
I2 = 1.5 A
