Welcome back K.E.N.N.Y.😈 — been a while! Let's pick up where you left off. 1. The relationship between energy (E), power (P), and time (t) is: E = P × t This means energy is the product of power and the time for which the power is used. 2. Given: Voltage V = 220\, V Power P = 1850\, W a) The energy dissipated by the element in 3\, min. Step 1: Convert time to seconds. t = 3\, min × 60\, s1\, min = 180\, s Step 2: Calculate the energy dissipated using the formula E = P × t. E = 1850\, W × 180\, s E = 333000\, J The energy dissipated is 333000 J. b) The current through the element. Step 1: Use the formula for power P = V × I, where I is the current. Rearrange to solve for I. I = (P)/(V) Step 2: Substitute the given values and calculate the current. I = 1850\, W220\, V I ≈ 8.409\, A The current through the element is approximately 8.41 A. c) The resistance of the element. Step 1: Use the formula for power P = (V^2)/(R), where R is the resistance. Rearrange to solve for R. R = (V^2)/(P) Step 2: Substitute the given values and calculate the resistance. R = (220\, V)^21850\, W R = 48400\, V^21850\, W R ≈ 26.162\, The resistance of the element is approximately 26.16 . Send me the next one 📸
