A light bulb with a resistance of 3Ω is connected to a 12V power source. Calculate the current flowing through the bulb.

Step 1: Identify the given values and the formula. The voltage (V) across the bulb is 12V. The resistance (R) of the bulb is 3Ω. We need to find the current (I). Ohm's Law states that V = IR. Step 2: Rearrange Ohm's Law to solve for current. I = V/R Step 3: Substitute the given values into the formula and calculate the current. I = 12V3Ω; I = 4A The current through the bulb is 4A.
