Question

Two wires X and Y are of equal length and have equal resistances. If the resistivity of X is more than
that of Y, which wire is thicker and why ? For the electric circuit given below calculate :

(i) Current in each resistor
(ii) Total current drawn from the battery and
(iii) Equivalent resistance of circuit

Answer 1

Answer:

X wire is thicker because resitivity of wire X is more than that of Y so that for making resistance equal we will have to increase thickness of wire X because resistance is indirectly proportional to area of cross section of wire
