Morning Sparta — let's get this done.

  1. a. (i) Step 1: Use the formula for power, P=V×IP = V \times I, where PP is power, VV is voltage, and II is current. 100 W=240 V×I100\, W = 240\, V \times I Step 2: Solve for II. I=100 W240 VI = \frac{100\, W}{240\, V} I=1024 AI = \frac{10}{24}\, \text{A} I=512 AI = \frac{5}{12}\, \text{A} I≈0.417 AI \approx 0.417\, \text{A}

    (ii) Step 1: Use Ohm's Law, R=VIR = \frac{V}{I}, where RR is resistance, VV is voltage, and II is current. R=240 V0.4166... AR = \frac{240\, V}{0.4166...\,A} Step 2: Calculate the resistance. R=240 V512 AR = \frac{240\, V}{\frac{5}{12}\, A} R=240×125 ΩR = 240 \times \frac{12}{5}\, \Omega R=48×12 ΩR = 48 \times 12\, \Omega R=576 ΩR = \boxed{576\, \Omega}
