A battery of emf 10 V and internal resistance `3 Omega` is connected to a resistor. If the current in the circuit is 0.5 A, what is the resistance of the resistors ? What is the terminal voltage of the battery when the circuit is closed ?

Explanation

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

### Step 1: Understand the Given Values
- EMF of the battery (E) = 10 V
- Internal resistance of the battery (r) = 3 Ω
- Current in the circuit (I) = 0.5 A

### Step 2: Calculate the Total Resistance in the Circuit
