Two coils of resistances `R_1 = 3 Omega and R_2 = 6.Omega `are connected in series across a battery of p.d. 12 V. Draw the circuit diagram. Find :
the total electrical energy supplied by the battery in 1 minute.

Explanation

To solve the problem step by step, we will follow these instructions:

### Step 1: Draw the Circuit Diagram
We have two resistors, \( R_1 = 3 \, \Omega \) and \( R_2 = 6 \, \Omega \), connected in series across a battery with a potential difference of \( 12 \, V \).
