Question
In the circuit shown, the cell has emf = 10 V and internal resistance = 1 Ω
Options
A.The current through the 3 Ω resistor is 1 A.
B.The current though the 3Ω resistor is 0.5 A
C.The current through the 4 Ω resistor is 0.5 A.
D.The current through the 4 Ω resistor is 0.25 A
Solution
Equivalent resistance Req = 10 Ω so current passing through battery and 3Ω resistance is
I =
= 1A Ans.
and current passing through 4 Ω is 0.25 A Ans.
I =
= 1A Ans.and current passing through 4 Ω is 0.25 A Ans.
