Question

Two resistors 10 ohm each can be connected to give a combined resistance of?

Answer 1

Answer:

Series = 20 ohms

Parallel = 5 ohms

Explanation:

Series combination:

When two resistors are connected in series, Req = R1 + R2

Here R1 = 10 ohms

R2 = 10 ohms

So Req when connected in series = 10+10

Req = 20 ohms

Parallel combination:

When two resistors are connected in parallel, 1/Req = 1/R1 + 1/R2

1/Req = 1/10+1/10

1/Req = 2/10

Req = 10/2

Req = 5 ohms

The two 10 ohms resistors can be connected in series to provide equivalent resistance of 20 ohms and in parallel to provide equivalent resistance of 5 ohms

⋄Two resistors 10 ohm each can be connected to give a combined resistance of?

_______________________________

✰Given :-

⋄ Let one resistors be (R) of 10 ohm.

⋄ Let another resistor be (R') of 10 ohm.

✰ To Find :-

⋄ Combined resistance.

❍ Solution :-

When two resistors connected in a series . Then resistance =R+R'

Resistance =R+R'

Resistance =10+10

Resistance =20ohm.

∴ These resistors are connected in series to give resistance of 20 ohm.
