Electrical power

Question

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

Moderate

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

Solution

$P = i^{2} R (i and R are same)$
So P will be same for given resistors.
