Physics Heating and Chemical Effect of Current Heating Effect of Current MCQ (Single Correct)

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

Unequal amounts of thermal energy may be produced

The temperature must rise equally in the resistors

The temperature must rise unequally in the resistors

Text Solution

Verified by Experts

The correct answer is:

(i and R are same)

So P will be same for given resistors.
