NEET Physics Current Electricity Questions Solved


Two batteries of e.m.f. 4V and 8 V with internal resistances 1 Ω and 2 Ω are connected in a circuit with a resistance of 9 Ω as shown in figure. The current and potential difference between the points P and Q are 

(1) 13A  and  3V

(2) 16A  and  4V

(3) 19A  and  9V

(4) 12A  and  12V

(1) Applying Kirchoff's voltage law in the given loop.

2i+841×i9i=0i=13A

Potential difference across PQ =13×9=3V
