Question

A storage battery of emf 8.0 V and internal resistance $1.5Ω$ is being charged by a 120 V dc supply using a series resistor of $6.5Ω$ . What is the terminal voltage (in V) of the storage battery during charging ?

Answer:

29

Solution:

Ans (29)

$112 = I (8)$

$I = 14$ Amp

T.p.d. = $V + I R$

$= 8 + 14 \times \frac{3}{2} = 29$ volt

Ans (29) 112 = I ( 8 ) I = 14 Amp T.p.d. = V + I R = 8 + 14 × 2 3 ​ = 29 volt
