Here are the calculations for question 1(b): b) A 100 W heater is connected to a 240 V mains supply. Calculate the: i) current drawn; Step 1: Use the formula for power, P = VI, where P is power, V is voltage, and I is current. I = (P)/(V) Substitute the given values: I = 100\, W240\, V I = 0.4166...\, A Rounding to two decimal places: I ≈ 0.42 A ii) resistance of the heater. Step 2: Use Ohm's Law, V = IR, where R is resistance. R = (V)/(I) Substitute the given voltage and the calculated current: R = 240\, V0.4166...\, A R = 576 Send me the next one 📸
