Two resistors having equal resistances ...

Two resistors having equal resistances are joined in series and a current is passed through the combination. Neglect any variation in resistance as the temperature changes. In a given time interval,

A

Equal amounts of thermal energy must be produced in the resistors

B

Unequal amounts of thermal energy may be produced

C

The temperature must rise equally in the resistors

D

The temperature must rise unequally in the resistors

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `P = i^(2) R` (`i` and `R` are same)
So `P` will be same for given resistors.
