Answer:
Remain the same.
Explanation:
If you doubled the voltage frequency in an RL series AC circuit, the inductive resistance would <u>remain the same</u>.
Answer:
1. They have less malfunctions
2. They can be operated from afar
3. Some are self-operated.
Explanation:
Answer:
surface temperature = 128.74⁰c
Explanation:
Given data
diameter of cable = 5 mm = 0.005 m
length of cable = 4 m
T∞ ( surrounding temperature ) = 20⁰c
voltage drop across cable ( dv )= 60 V
current across cable = 1.5 A
attached to this answer is the comprehensive analysis and solution to the problem.
The assumption made is not a good one since the calculated Ts ( surface temperature ) is very much different from the assumed Ts
