Answer:
0.25 ohm is the correct answer
Explanation:
because when 1 is divided by 4 the answer is 0.25
Answer:
Equivalent resistance =1/16
Explanation:
When a wire of resistance R is cut into n equal pieces then the resistance of each part =R/n
Therefore, resistance of each piece =1/4
R1=R2=R3=R4=1/4
The equivalent resistance when the pieces are kept in parallel
1/R= 4 +4 +4+ 4=16
R=1/16
