WebIn calculating the power in the circuit of Figure 19.21, we used the resistance and Ohm’s law to find the current. Ohm’s law gives the current: I = V / R, which we can insert into … WebAn HVDC system can transmit a maximum voltage of 250 kV and a maximum current of 1000 A. Evaluate the maximum power transfer capacity in the system. P = V×I. P = 250,000 volts×1000 amperes. P = 250,000,000 watts. P = 250 MW. The maximum power transfer function in the HVDC is therefore equal to 250 MW.
