Two resistors having equal resistances are joined in series and a current is passed through the combination.

Monjur Alahi

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 may rise equally in the resistors.

A steel wire and a copper wire of equal length and equal cross-sectional area are joined end to end and the combination is subjected to a tension.

(a) Since both types of wires are joined end to end, the same load will be on the cross-sections of them. If the load = F and the area of...

A battery of emf 100 V and a resistor of resistance 10 kΩ are joined in series. This system is used as a source to supply current

But we were asked the current value in the question not the proof. Moreover u have used the wrong value of resistance as given in the question(R=10k ohm not 100k...
