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]
