A resistor of resistance R is connected to a cell of internal resistance 5 Ω Ω . The value of R is varied from 1 Ω Ω to 5 Ω Ω . The power consumed by R:
Text Solution
Verified by ExpertsThe correct answer is:
A
P = 
R
= 0 at R = 5 Ω Ω , so power is maximum at R = 5 Ω Ω
Therefore increase continuously till R = 5 Ω Ω .
