A 5 V battery of negligible internal resistance is connected across a 200 V battery and a resistance of \[39\text{ }\Omega \] as shown in the figure. The value of current is
A)5 A
B)3 A
C)4 A
D)7.8 A
Correct Answer:
A
Solution :
(a) 5 A Apply KVL, \[-39l-200+5=0\Rightarrow 39l=195\Rightarrow l=5\,A\]
