KCET2019PhysicsCurrent Electricity
The variation of terminal potential difference ( (V) ) with current flowing through as cell is as shown The emf and internal resistance of the cell are
Options
- A( 6 , 2 )
- B( 3 ~V , 2 )
- C( 6 ~V , 0.5 )
- D( 3 ~V , 0.5 )
Correct answer
D. ( 3 ~V , 0.5 )
Step-by-step solution
(D) V=E- Ir This is the form of : y=m x+c When I=0, V=E=3 ~V When V=0, r= E 1 = 3 6 =0.5
