Morning Sparta — let's get this done. 1. a. (i) Step 1: Use the formula for power, P = V × I, where P is power, V is voltage, and I is current. 100\, W = 240\, V × I Step 2: Solve for I. I = 100\, W240\, V I = (10)/(24)\, A I = (5)/(12)\, A I ≈ 0.417\, A (ii) Step 1: Use Ohm's Law, R = (V)/(I), where R is resistance, V is voltage, and I is current. R = 240\, V0.4166...\,A Step 2: Calculate the resistance. R = 240\, V(5)/(12)\, A R = 240 × (12)/(5)\, R = 48 × 12\, R = 576\, Send me the next one 📸
