If der r 2 or more wires protruding from a single point, then da current is split. When current is split, da value of current is not da same everywhere in da circuit. Da only circuit arrangement, where dis is not da case is arrangement D. In D, a single wire is connecting every meter, so current is same throughout circuit

There are total of 8.5 waves right ?
So here
0.01 for 1 box
so for 6 box what is the time ? (6 coz, 8.5 cycles occurred in those 6 box) = 0.06
so T = 0.06 / 8.5 = 0.007 sec
so now f = 1 / T = 1 / 0.007 about to 140 so B
