Current Electricity Charging Discharging Of Capacitors Question 578

Question: The magnitude and direction of the current in the circuit shown will be

[CPMT 1986, 88]

Options:

A) $ \frac{7}{3} $ A from a to b through e

B) $ \frac{7}{3} $ A from b to a through e

C) 1A from b to a through e

D) 1A from a to b through e

Show Answer

Answer:

Correct Answer: D

Solution:

Since $ E _{1}(10,V)>E _{2}(4V) $ So current in the circuit will be clockwise. Applying Kirchoff’s voltage law $ -,1\times i+10-4-2\times i-3i=0 $

Therefore $ i=1A(a,\text{to }b\text{ via }e) $ \ Current $ =\frac{V}{R}=\frac{10-4}{6}=1.0,ampere $
