Answer:

In series combination

RS = RR R 1 2 + + .... n

RS = RR n + ..... times

RS = nR

In parallel combination:

R

1

P

..... RR R

11 1

1 2 n

= + +

R

1

P

..... RRR n

111 = +++ + times

R

1

P

..... times

R

1 1 n = + +

R

1

P R

n =

RP n

R =

ii. Given:

R1 = 3 Ω

R2 = 4 Ω

R3 = 12 Ω

R

1

RRR

111

123

= + + 3

431 = + +

R 8

12 = Ω 2

3 = Ω

= 1 5. Ω
