Here's the solution for question 1(b): b) i) To calculate the current drawn, we use the formula relating power, voltage, and current: P = V × I. Step 1: State the given values and the formula. Given: Power (P) = 100\, W Voltage (V) = 240\, V Formula: I = (P)/(V) Step 2: Substitute the values into the formula and calculate the current. I = 100\, W240\, V I = 0.4166...\, A I ≈ 0.42 A ii) To calculate the resistance of the heater, we can use the formula relating power, voltage, and resistance: P = (V^2)/(R). Step 1: State the given values and the formula. Given: Power (P) = 100\, W Voltage (V) = 240\, V Formula: R = (V^2)/(P) Step 2: Substitute the values into the formula and calculate the resistance. R = (240\, V)^2100\, W R = 57600\, V^2100\, W R = 576 Send me the next one 📸
