Question

what is ammeter reading in the circuit?​

Answer 1

Answer:

ammeter in series: An Ammeter (A) is placed in series to measure current. All of the current in this circuit flows through the meter.The Ammeter would have the same reading if located between points d and e or between points f and a ,as it does in the position shown

Answer 2

R1 and R2 are in series

so R= R1 + R2 =3+3=6

but parallel to r3

so 1/R =1/3+ 1/6=3/6=1/2

R=2

now all are in series so 2+.5+.5=3

v=iR

I =v/R=3/3=1A
