A) 1
B) 4
C) 2
D) 3
Correct Answer: B
Solution :
When wire is cut into two equal parts then power dissipated by each part is \[2{{P}_{1}}\] So their parallel combination will dissipate power \[{{P}_{2}}=2{{P}_{1}}+2{{P}_{1}}=4{{P}_{1}}\] Which gives \[\frac{{{P}_{2}}}{{{P}_{1}}}=4\]You need to login to perform this action.
