Step 1: Identify the given values. The power of the electric bulb is P = 75 \, W. The operating voltage is V = 240 \, V. Step 2: Use the formula relating power, voltage, and resistance. The formula for power in terms of voltage and resistance is: P = (V^2)/(R) To find the resistance R, we can rearrange the formula: R = (V^2)/(P) Step 3: Substitute the given values into the formula. R = (240 \, V)^275 \, W Step 4: Calculate the resistance. R = 57600 \, V^275 \, W R = 768 \, The resistance of the heating element is 768 .
