A 6 V, 12 W lamp is connected in series with a resistor R and a source of voltage 12 V.
What is the current flowing through the circuit?

Explanation

To solve the problem, we need to determine the current flowing through the circuit with the given lamp and resistor. Here’s a step-by-step solution:

### Step 1: Identify the given values
- Voltage of the lamp (V_lamp) = 6 V
- Power of the lamp (P_lamp) = 12 W
- Source voltage (V_source) = 12 V

### Step 2: Use the power formula
