Find the reading of the ideal ammeter connected in the given circuit. Assume that the cells have negligible internal resistance

A

2.5 A

B

`5A `

C

`2 A`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
c.
The current through ammeter
`I = I_4 - I_3 + I_2 - I_1`
` = (6-0)/(2) - ((8-6)/4) + (6-4)/4 - (14-6)/8`
`= 3 - 1/2 + 1/2 -1 = 3 -1 = 2A` .
