Is there any difference in AC current/ DC current carrying
capacity of a conductor .What can be maximum current
handling capacity of a 2.5mm stranded cu cable when
connected to AC and DC supply.
Answer Posted / percy
yes there is a difference in current carrying capacity as
dc current spreads in whole conductor area and the ac
current density is not uniform and hence the resistance in
ac will be high in case of AC

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
