Two heating wires of equal length are first con nected in series and then in parallel to a constant voltage source. The rate of heat produced in the two cases is

A

`2:1`

B

`1:2`

C

`4:1`

D

`1:4`

Text Solution

Verified by Experts

The correct Answer is:
D
For V = constant
`H prop 1/R rArr H_(1)/H_(2) = R_(2)/R_(1) = (R//2)/(2R) = 1/4`
