Question

5. (a) How can three resistors of resistances 20,30 and 6 Abe connected to give a total
resistance of(i) 4 (ii) 12

(c) Find the ratio of the both resistances when diameter is doubled.​

Answer 1

Answer:

(a) if we connect the all three resistors in parallel connection then we get 4

Answer 2

Answer:

In PARALLEL, 1/R=1/R1+1/R2+1/R3

=1/20+1/30+1/6

=3+2+10/60

=15/60

=60/15

=4 ohm

Three resistors connected in parallel

c) 1:4
