Question

A battery having 12 V emf and internal resistence 3 is connected to a resistor. If the current in the circuit is 1A, then the resistence of resistor and lost voltage of the When circuit is closed will be.

Answer 1

Answer:

I=RV

=I=3+R12

⇒3+R=12

R=9Ω

Terminal voltage =E−I

                             =12−3×1

                             =12−3=9V

 

Answer is  (9,9)
