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,

Options

A. unequal amount of thermal energy may be produced
B. equal amount of thermal energy may be produced
C. the temperature may rise equally is the resistance
D. the temperature may must equally is the resistance

Answer

b,c

Explanation

Heat produced, `H = I^(2) Rt`. since `I,R and t` are same for the two resistors, hence equal amount of thermal energy must be temperature Also `H= mc theta`, therefore the temperature may rise equllty in the resistors if there sp-beat in same otherwise not.
