Question

b) Three resistors having resistances of 5Ω, 12Ω and 6Ω are connected in series. What is the effective resistance in the circuit?​

Answer 1

Answer:

The arrangement is shoen.

For arrangement of n resistors in parallel , the equivalent resistance is

n

R

.

Hence we get three resistances

3

7.5

=2.5Ω and

5

8

=1.6Ω and

3

6

=2Ω in series.

Hence finally equivalent resistance is R=2.5+1.6+2=6.1Ω
