Question

What is the current if 4ohm and 2ohm resistors are connected in series and 6v potential difference is applied.

Answer 1

Answer:

we know that

current = potential difference x resistance.

here the total resistance is 4 + 2 = 6 ohm as the resistors are connected in series.

substituting the values we have, we get,

current = 6 x (4+2)

            = 6 x 6

            = 36 A

hope this helps you : )

Explanation:

Answer 2

Answer:-

• R1=4ohm
• R2=2ohm

Finding Equivalent Resistance:-

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

$\\ \qquad\sf\longmapsto R=4+2$

$\\ \qquad\sf\longmapsto R=6\Omega$

• Potential difference=V=6V
• Current=I=?

According to ohms law

$\boxed{\sf \dfrac{V}{I}=R}$

$\\ \qquad\sf\longmapsto I=\dfrac{V}{R}$

$\\ \qquad\sf\longmapsto I=\dfrac{6}{6}$

$\\ \qquad\sf\longmapsto I=1A$
