Two indential heated produce heat `H_(1)` in time `t` when connected in parallel across the main supply. They produce heat `H_(2)` in time `t` when connected in series. Then `H_(1)//H_(2)` is

A

`1/4`

B

4

C

`1/2`

D

2

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(1) = (V^2)/(R//2) t , H_(2) = (V^2)/(2R) t`
`(H_1)/(H_2) = 4` .

There are two metallic wires of same material, same length but of different radii. When these are connected to an ideal bettery in series, heat produced is H_(1) but when connected in parallel, geat produced is H_(2) for the wsame time.Then the correct statement is

Two metallic wires of the same material and same length have different diameters. If we connect them in series across a battery, the heat produced is H _(1). If we connect them in parallel to the same battery the heat produced during the same time is H_(2). From the above, we infer that

When two identical batteries of internal resistance 1Omega each are connected in series across a resistor R, the rate of heat produced in R is J_1 . When the same batteries are connected in parallel across R, the rate is J_2 = 2.25 J_2 then the value of R in Omega is
