Question

Two resistors of 20 ohm and 30 ohm are connected in series. Calculate the equivalent resistance.

Answer 1

Answer:

Given:

Two resistors of 20 ohm and 30 ohm are connected in series

To Find:

Equivalent resistance

Solution:

Let us take,

$\implies \sf R_1 = 20$ Ω

$\implies \sf R_2 = 30$ Ω

According to the question,

They are connected in series

We Know That,

Equivalent resistance in Series connection

$\green{\boxed{\boxed{\sf R_s = R_1 + R_2}}}$

$\sf \implies R_s = 20 + 30$ Ω

$\implies \sf R_s = 50$ Ω

Equivalent resistance is 50 Ω

Additional Information:

⇒ If Resistors are connected in Parallel

⇒ Then the Equivalent resistance in Parallel connection

⇒ It can be calculated by using the formula

$\orange{\boxed{\boxed{\sf \dfrac{1}{R_p} = \dfrac{1}{R_1} + \dfrac{1}{R_2}}}}$
