Question

5 ohm,10 ohm 20V find the parallel resistance and current​

Answer 1

Answer:

1/Rp = 1/R1 + 1/R2

1/Rp = 1/5 + 1/10

1/Rp = (2+1)/10

1/Rp = 3/10

Rp = 10/3 ohm

V = IR

20 = I 10/3

I = 6 A

Answer 2

Step-by-step explanation:

$\\ Here \: R_{1} = 5Ω \: \: \: R_{2} = 15Ω \: \: V=20V\\ \frac{1}{R} = \frac{1}{R_{1}} + \frac{1}{R_{2}} \\\\= \frac{1}{5} + \frac{1}{10} \: \: \:\\ \\ = \frac{3}{10}\\ \\ R = \frac{10}{3} Ω = 3.34Ω \\ \\ current\: I= \frac{V}{R} = \frac{20}{3.34} = 6A$
