MCQ

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

✓
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

✓

Answer

Correct option: A.

Equal amounts of thermal energy must be produced in the resistors

a
$P = {i^2}R$ ($i$ and $R$ are same)

So $P$ will be same for given resistors.
