# In the circuit di

Answer :

(i) Let the total resistance of the circuit =R

As the connections are parallel. So the total resistance will be

1/R=1/R1+1/R2

R2=3+2=5ohms

R1=5ohms

1/R=1/5+1/5

1/R=2/5

R=2.5ohms

(ii) Current shown by the ammeter A will be equal to the current following in the circuit.

I=V/R=4/(2.5)

=1.6amps
