Question

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 (A) 6 V, 2 Ω (B) 3 V, 2 Ω (C) 6 V, 0.5 Ω (D) 3 V, 0.5 Ω

V=E-lr This is the form of: y = mx + c When I = 0, V = E = 3v When V = 0, r=(E/I)=(3/6)=0.5 Ω

Q. 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

$6 V, 2Ω$

$3 V, 2Ω$

$6 V, 0.5Ω$

$3 V, 0.5Ω$

$V = E - l r$
This is the form of : y = mx + c
When I = 0, V = E = 3v $Wh e n V = 0, r = \frac{E}{I} = \frac{3}{6} = 0.5Ω$

6V,2Ω

3V,2Ω

6V,0.5Ω

3V,0.5Ω

V=E−lr This is the form of : y = mx + c When I = 0, V = E = 3v WhenV=0,r=IE​=63​=0.5Ω

$6 V, 2Ω$

$3 V, 2Ω$

$6 V, 0.5Ω$
