If a resistance of `15` ohm is cut into three equal pieces and then connected at first in series and then parallel combination.What will be the equivalent resistance in both cases

Answer 2

Answer:

Explanation:

Three Resistors of 12, 15 and 20 ohm.

To Find:-

The equivalent resistance in series.

The equivalent resistance in parallel.

Formulae Used:-

In Series,  

In Parallel,  

Where,  

Req = Equivalent Resistance.

R1, R2 and R3... are given Resistors.

So Here,

Req = ?? [to Find]

R1, R2 and R3 = 12, 15 and 20 ohm respectively.

Case I:-

Resistors are connected in series:-

Therefore in series combination equivalent resistance is 47 ohm.

Case II:-

Resistors are connected in series:-    

Therefore in parallel combination equivalent resistance is 5 ohm
