Question

When Resistance
are connected in Series form
R1 =2 ohm, R2= 5 ohm
and R3= 3 ohm and also
connected to parallel form find equivalent
Resistance in both case​

Answer 1

$\huge\mathcal{\underline{\color{purple}Answer}}$

====================================

☆When connected in SERIES

Given : R1= 2ohm, R2= 5ohm, R3= 3ohm

Formula: $R=R1+R2+R3$

⇒$R=2+5+3$

⇒$R=$$10$

⇒Hence Resistance in SERIES= 10ohm

===================================

☆When connected in PARALLEL

Given : R1= 2ohm, R2= 5ohm, R3= 3ohm

Formula:  $\frac{1}{R}=\frac{1}{R1} +\frac{1}{R2} +\frac{1}{R3}$

⇒ $\frac{1}{R} =\frac{1}{2} +\frac{1}{5} +\frac{1}{3}$

⇒ $\frac{1}{R} =\frac{(15+10+6)}{30}$

⇒ $R=$$\frac{31}{30}$

⇒Hence Resistance in PARALLEL 0.967 Ohms
