The reading of the ideal ammeter will be (Resistance of ideal ammeters is zero)

Options

A. `5/6 A`
B. `6/5 A`
C. `3/2 A`
D. `2/3 A`

Answer

A

Explanation

Equivalent resistance for given circuit is given by,
Req = `3 || 6 + 2 = 2 + 2 = 4 Omega`
Current from Battery, `I = V/R_(eq) = 10/4 = 2.5 A`, where V & `R_(eq)` represents voltage and equivalent resistance of the circuit.

`I_(1) = 2.5 xx 3/(3+6) = 5/6 A`
