In the circuit shown below E(1) = 4.0 V,...

In the circuit shown below `E_(1) = 4.0 V, R_(1) = 2 Omega, E_(2) = 6.0 V, R_(2) = 4 Omega` and `R_(3) = 2 Omega`. The current `I_(1)` is

A

1.6A

B

1.8A

C

2.25A

D

1A

Text Solution

Verified by Experts

The correct Answer is:
B
For "loop" `(1) -2i_(1) -2(i_(1) - i_(2))+4`=0`rArr` `2i_(1) –i_(2)` = 2
For "loop"`(2) -4i_(2) -2(i_(1) - i_(2))+6`=0`rArr` `3i_(1) –i_(2)` = 3
After "solving" equation (1) and (11) we get `i_(1)` = 1.8 A and `i_(2)` = 1.6 A.
