Question

Three resistors 10,20,and 30Bon are
connected in
(a) series
(b) parellel find the presultant resistance
in the circuit.​

Answer 1

Explanation:

(a)R1=10 ohm

R2=20 ohm

R3=30 ohm

R for series=R1+R2+R3

10+20+30

=60 ohm

(b)R1=10 ohm

R2=20 ohm

R3=30 ohm

R for parallel=1/R1+1/R2+1/R3

1/R=1/R1+1/R2+1/R3

1/R=1/10+1/20+1/30

1/R=6+3+2/30

1/R=11/30

R=30/11 ohm
