Question

Q What is the current through the 20 ohm resistor on the left of the 20 ohm resistor on the left of 6V cell in figure​

Answer 1

Answer:-

• R1=20ohm
• R2=20ohm
• V=6V
• Current=I=?

First find Equivalent Resistance

$\boxed{\sf R=R_1+R_2}$

$\\ \rm\hookrightarrow R=20+20$

$\\ \rm\hookrightarrow R=40\Omega$

According to ohms law

$\\ \rm\hookrightarrow \dfrac{V}{I}=R$

$\\ \rm\hookrightarrow I=\dfrac{V}{R}$

$\\ \rm\hookrightarrow I=\dfrac{6}{40}$

$\\ \rm\hookrightarrow I=0.1A$
