Question

38. A uniform wire of resistance 30Ω is cut into three equal parts . these parts are now connected in parallel. Then the equivalent resistance of the combination is


​

Answer 1

Answer:

R=30ohm

R1=10ohm

R2=10ohm

R3=10ohm

R eq.=R/n(R1,R2,R3 are same in magnitude)(n=no.of resistance)

10/3=3.34ohm

Answer 2

Answer

3.33..ohm

Explanation:

Total Resistance=30 ohm

If cut into 3 equal parts=30/3

=10

Equivalent resistance in

parellel for 3 equal parts=10/3

=3.33..ohm
