Q. 3 B4.8( 6 Votes )

# In the circuit diagram shown below, find:(i) Total resistance.(ii) Current shown by the ammeter A (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
