PE Unreasonable Results (a) What current is needed to transmit 1.00×10? MW of 2? power at 480 V? (b) What power is dissipated by the transmission lines if they have a 1.00 - ? resistance? (c) What is unreasonable about this result? (d) Which assumptions are unreasonable, or which premises are inconsistent?
Step-by-step solution Given: Power = 1.00×10 MW Voltage = 480 V Resistance = 1.00 - 6 1 MW = 10 Watt Calculate: Power is dissipated by the transmission lines= Comment on unreasonable,assumptions = Step 1 of 5 Power is defined as the rate at which energy is consumed. The relation for power P, electric current I and voltage V is given by equation (1) P = VI …………………..(1)
