Question

five resistors are connected in a circuit shown in figure find the ammeter reading when the circuit is closed =R1 =3 ,R2 =3 , R3=4 , R4=3 , R5=3​

Answer 1

Answer: 1 Ampere

Given data states the 5 resistors connected with the value,

= 3 Ω;  = 3 Ω ;  = 3 Ω;  = 0.5 Ω and  = 0.5 Ω.

As shown,  the  and  are in series connection, therefore,

R' =   = 3 + 3 = 6 Ω

And then R' and  are now in parallel connection, thereby

Ω

And then R'' with  and  are in series, thereby

Total

Ω.

Therefore,

Current

=1 Ampere.
