Question

If each resistance in the figure is of 9 2 then reading of ammeter is​

Answer 1

Answer:

1 A

Explanation:

Net resistance of resistors after ammeter is

Since they are connected in parallel then

1/R'=1/9+1/9+1/9+1/9+1/9

R'=9/5 Ω

Similarly net resistance of resistors before ammeter is

R"=9/4 Ω

Net resistance of the circuit is

R'+R"= 9/4+9/5

R=9Ω

By ohm's law

I=V/R

I=9/9

I=1 A
