Question

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

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

Answer 1

The correct option is B $15V$

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.
