Asked by JENE


A cattleman has installed a new electric fence. The cows keep escaping because they are not deterred by the low power they experience when touching the fence. There are two dials on his controls. Would you tell him to change the amperage or voltage? Support your answer with information from the lesson.


Answered by Henry
Increasing the voltage increases the current and power(P = E*I); therefore, the voltage should be increased.
