Question

Q.2: What will be the equivalent resistance if 5Ωand20Ω5Ωand20Ω are connected in parallel?
with full explanation....​

Answer 1

Explanation:

$\frac{1}{r} = \frac{1}{20} + \frac{1}{2 0 } + \frac{1}{5} + \frac{1}{5} = \frac{1}{2} ohm$

r = 2 ohm

Answer 2

answer is 2 ohm

• because 5ohm , 20ohm , 5 ohm and 20 ohm are connected in Parallel combination
• so as per formula 1 / R eq = 1/R1 + 1/R2 + 1/R3 + 1/R4

1/ R eq = 1/5 + 1/20 + 1/5 + 1/20

= 10/20

= 1/2

R eq = 2 ohm
