Question

What is the answer of 4 ohm, 6 ohm ,30 ohm in parallel

Answer 1

The answer is 2. 22....

Answer 2

Answer:

2.22Ω

Explanation:

$R_{A}$= 4Ω

$R_{B}$= 6Ω

$R_{C}$= 30Ω

In a parallel connection,

$\frac{1}{R}$ =$\frac{1}{R_{A} }$ +$\frac{1}{R_{B} }$ [/tex]) + $\frac{1}{R_{C} }$

$\frac{1}{R}$ = $\frac{1}{4}$ +$\frac{1}{6}$ + $\frac{1}{30}$

$\frac{1}{R}$ =  $\frac{14+10+2}{60}$

$\frac{1}{R}$ = $\frac{9}{20}$

R = $\frac{20}{9}$

R ≈ 2.22 Ω
