Question

A battery and three lamps are connected as shown:

Which of the following statements about the currents at X, Y and Z is correct?
(a) The current at Z is greater than that at Y.
(b) The current at Y is greater than that at Z.
(c) The current at X equals the current at Y.
(d) The current at X equals the current at Z.

Solution

(b) The current at Y is greater than that at Z.
This is so because Y alone will offer less resistance.

Q. Equal currents are flowing in three infinitely long wires along positive x,y and z directions.The magnetic field at a point (0,0,-a) would be (i=current in each wire):

Q. Two parallel wires carrying equal currents in opposite directions are placed at

x = \pm a

parallel to y-axis with

z = 0
