12xl06 240 = 50, 000 A It is unwise to carry iArwer at such a high current level because : (1) Cost of power line. ... sends equal amount of charge q in half-time period, i.e. 772 is known as average current and it is represented by lmv therefore 9 = a#39;, avj (i) As the charge flown during one half-cycle of an ac is ... Ans. As Xc - 1/0)C and here to = 2nf = 0 so the reactance of 1 ^F capacitor is infinite for a dc current.
