Question

There are three resistance 5$\Omega$, 6$\Omega$ and 8 $\Omega$ connected in parallel to a battery of 15 V and of negligible resistance. The potential drop across 6$\Omega$ resistance is

• A. 10 V
• B. 15 V
• C. 20 V
• D. 8 V

Answer 1

The correct option is B 15 V

Answer is B.

Components connected in parallel are connected so the same voltage is applied to each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component. In this case, it is a parallel, the voltage across each component will remain the same as 15 V.
Hence, the potential drop across the 6 ohms resistor is 15 V.
