Question

Two resistances 3 ohm and 6 ohm are connected in parallel calculate the equivalent resistance

Answer 1

Answer:

1.2 ohm

Explanation:

1 / R = 1 / 3 + 1 / 6

R = 6 / 5 ohm

Answer 2

Answer:

Equivalent resistance is 2 Ω.

Explanation:

Equivalent resistance (parallel connection) :

$R\;=\;\frac{R_1R_2}{R_1+R_2}$

Here :

$R_1$ = 3 Ω

$R_2$ = 6 Ω

So :

• $\frac{3\times6}{3+6}$

• $\frac{18}{9}$

• $2$

∴ Equivalent resistance is 2 Ω.
