If the current of the bulb increases will it short. When the current will inc the resistance should decrease and it should not produce much heat energy so why does it short?

don't how to draw this for you as I can't do it on the computer but the amplitude will be less and phase difference is 5 blocks apart

since 30 blocks = 360

Ya I know and I have drawn it. I wanted to compare it. Right its 5 blocks away and my amplitude was 7.

Can someone please tell me how do you solve questions in which uncertainties are given? :/

ANYBODY? :'(
P and N are both in the horizontal direction, opposite to each other, with P facing the left and N facing the right (because P is positively charged and the direction of the electric field is to the right, so it would obviously go to the left).

(a) (i) A & C

Treat A to C as a straight line and forget everything else. The resistance will only be R.

(ii) B & X

The total resistance in parallel here is R/2, so the resistance at any point there is R/2.

(iii) This is equal to the total resistance in series + total resistance in parallel, that's 2R + R/2 = 2.5R.
