Question

3) If two resistors of 25 ohm and 15ohm is a Connected in series and then also in parallel
calculate the effective resistance in both the
types. Comment on the value
resistance
of the total​

Answer 1

Answer:

Series- 25+15= 40 ohm (Rt= R1+R2)

Parallel- 1/25+1/15= 3+5/75

=8/75

therefore, 75/8 = 9.375 ohm (1/Rt= 1/R1+1/R2)

Explanation:

Do we really need one?

Answer 2

Answer:I hope this will help u.

Explanation:In series

Rs=R1+R2

Rs=25+15

Rs=40 ohm

In parallel

Rp=1/R1+1/R2

Rp=1/25+1/15

Rp=3+5/75

Rp=8/75

Rp=0.1
