Three equal resistors connected in series across a source of emf together dissipate 10W of power. What would be the power dissipated if te same resistors are connected in parallel across the same source of emf?

Options

A. 25 W
B. 80 W
C. 45W
D. 90 W

Explanation

To solve the problem step by step, we will analyze the power dissipated by the resistors in both series and parallel configurations.

### Step 1: Understand the given information
We have three equal resistors, each with resistance \( R \), connected in series across a source of emf. The total power dissipated in this configuration is given as \( P = 10 \, \text{W} \).

### Step 2: Calculate the equivalent resistance in series
When resistors are connected in series, the equivalent resistance \( R_{\text{eq, series}} \) is given by:
\[
