Question

Wha is the effeçtive resistance if 6 ohm and 2 ohm resistors are connected in parallel

Answer 1

• R1=6 ohm
• R2 = 2 ohm

${\boxed{\sf \dfrac{1}{R_p}=\dfrac{1}{R1}+\dfrac{1}{R2}}}$

$\sf\longrightarrow \dfrac{1}{R_p}=\dfrac{1}{6}+\dfrac{1}{2}$

$\sf\longrightarrow\dfrac{1}{R_p}=\dfrac{1+3}{6}$

$\sf\longrightarrow \dfrac{1}{R_p}=\dfrac{4}{6}$

$\sf\longrightarrow R_p = \dfrac{6}{4}$

$\sf\longrightarrow R_p= 1.5\Omega$
