What is the voltage directly proportional to in a series circuit? |
In a series circuit, the voltage is directly proportional to the resistance |
|
|
What is the current inversely proportional to in a parallel circuit |
In a parallel circuit, the current is inverselyy proportional to the resistance |
|
|
Name some reasons to use a three-wire single phase system |
It saves copper and aluminum reduces voltage drop and provides a 240 volt circuit |
|
|
What happens if the neutral of an unbalanced three wire system is open? |
The circuit becomes a 240 volt series circuit |
|
|
Why does more than half the total voltage drop across the line with the smaller load? |
Because it has a higher resistance |
|
|
What happens to a voltage of a neutral of an unbalanced? Three wire system is open and the circuit becomes a 200 volt series circuit |
The line with the smaller load voltage rises above 120 v |
