Question

find the equivalent resistance and total current

Answer 1

$\huge\underline{\underline{\bf \green{Solution-}}}$

Refer to the Attachment

✰ Series

$\implies{\bf \blue{R_{eq_1}=R_1+R_2 }}$

$\implies{\sf R_{eq_1}= 30+30 }$

$\implies{\sf R_{eq_1}= 60\:Ω}$

✰ Parallel

$\implies{\bf \blue{\dfrac{1}{R_{eq_2}}=\dfrac{1}{R_1}+\dfrac{1}{R_{eq_1}}}}$

$\implies{\sf \dfrac{1}{R_{eq_2}}=\dfrac{1}{30}+\dfrac{1}{60}}$

$\implies{\bf \red{ R_{eq_2}=20\:Ω}}$

❏ Total Current ( I ) ➝

✪$\large{\boxed{\bf \blue{V = IR} }}$

$\implies{\sf I = \dfrac{2}{20} }$

$\implies{\bf \red{ I = 0.1\:A} }$

$\huge\underline{\underline{\bf \green{Answer-}}}$

Total Resistance ${\bf \red {20Ω}}$

Total Current ${\bf \red{0.1\:A}}$
