Question

when two resistance 6 ohm and 12 ohm are connected in parallel,Find the effective resistance?​

Answer 1

The effective resistance is

= (6*12)/(6+12)

= 72/18

= 4 ohms....

Answer 2

Given :

R₁ = 6 ohm

R₂ = 12 ohm

To Find :

Effective resistance

Solution :

Two resistors are said to be connected in parallel if one end of each is connected to a common point, and the other end to another point.

Equivalent / Effective Resistance (R) in a parallel combination can be given as -

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

So, the effective resistance (R) when R₁ = 6 ohm and R₂ = 12 ohm is

R = $\frac{6 * 12}{6 + 12}$

R = $\frac{72}{18}$

R = 4 ohm

Therefore, the effective resistance is 4 ohm.
