If a 15-ohm resistor is connected in parallel with a 30 ohm-resistor, the equivalent resistance is?

Answer:

Explanation:

in parallel combination equivalent resistence =

1/R=1/R1 + 1/R2

1/2=1/15+1/30

1/2=1*2+1*1/30

1/R=3/30

R*3=30*1

R=30/3

R=10 ohm

Explanation:

Equilibrium resistance=1/R1 +1/R2

[tex] = \frac{1}{15} + \frac{1}{30} \\ = \frac{2 + 1}{30} \\ \frac{1}{r} = \frac{3}{30} \\ resistance \: = \frac{30}{3} \\ = 10 \: ohms[/tex]
