Question

In the figure given below, the current flowing through 10 $\Omega$ resistance is

• A. 1.2 A
• B. 1.2 A
• C. 0.8 A
• D. 0.4 A

Answer 1

Answer: (A)

1.2 A

Answer 2

The 10 $\Omega$ resistor is in parallel with the series combination of 15 $\Omega$, 3 $\Omega$, and 0.5 $\Omega$ resistors. The voltage across a parallel branch is equal to the source voltage. If we assume a typo in the question and the source voltage is 12 V (instead of 20 V), the current through the 10 $\Omega$ resistor is $12V / 10\Omega = 1.2 A$.
