Questions
The long distance transmission of electrical energy is done at
a
High potential and low current
b
Low potential and high current
c
High potential and High current
d
Low potential and low current
detailed solution
Correct option is A
The higher the voltage used to power a load, the lower the current and the lower the voltage used, the higher the current flowing through the load. The power loss due to a resistive load is directly proportional to the square of the current flowing through it. The choice of voltage and current during transmission is to reduce the power losses in the conducting medium.Talk to our academic expert!
