Question

12. The two resistances are first 5ohm and second 10ohm. What will be their value in parallel? *

a. 15ohm

b. 5ohm

c. 4.33ohm

d. 3.33ohm​

Answer 1

Answer:

lets first see the formula is

$\frac{1}{R}= \frac{1}{R_{1} }+\frac{1}{R_{2} }$

Explanation:

$\frac{1}{R}= \frac{1}{5}+\frac{1}{10} }$

$\frac{1}{R}= \frac{3}{10}$

$R=\frac{10}{3}$ omh

R=3.333 omh

so d is correct option
