Question

keep a uniform wire of resistance R is cut into 4 equal parts and attached in parallel combination the equivalent resistance is​

Answer 1

Answer: Reduces 16 times.

Explanation:

Resistance is directly proportional to length and inversely proportional to area of cross section of the wire. Therefore here the length is reduced 4 times and area is increased 4 times. Therefore resistance decreases 16 times.

R ∝L/A

Answer 2

Answer:

it will be R X 4 (if R=1 then RX4= 4)

Explanation:

in parallel combination the circuit continues to flow current even if one R is disconnected .
