Question

Two resistors each of 10ohm are placed in series

Answer 1

Answer:

both the resistors of 10 ohm are in series

the formula for calculating resistance in series is given in picture

so,10+10=20 ohm

I HOPE THIS HELPS YOU

PLEASE MARK ME AS BRAINLIEST ANSWER.

Answer 2

Answer:

20 ohms

Explanation:

Given :

• Two resistors of 10 ohms are connected in series combination

To find :

• Equivalent resistance across the circuit

Knowledge time :

Equivalent resistance when resistors are in series = R1+R2

Equivalent resistance when resistors are in parallel = 1/equivalent resistance = 1/R1+1/R2

So here both of them are connected in series

Equivalent resistance = 10+10

Equivalent resistance = 20 ohms

The equivalent resistance across the circuit is equal to 20 ohms

Out of box :

• Ohms law = V=I×R

Where v = potential difference

I = current

R = resistance

• Coulombs law = Q=I×t

Where q = charge

I = current

T = time
