3.10 DC Voltage Flashcards
1
Q
What voltage are lead acid battery cells?
A
2V when charged
1.83V final discharge voltage
2
Q
What voltage are Nickel Cadmium battery cells?
A
1.2V when charged
1V when discharged
3
Q
When is the electrolyte level in a Nickel Cadmium battery at its lowest?
A
After discharge
4
Q
By connecting like power sources in parallel the voltage remains constant, but the current in the power sources…….
A
Decreases
5
Q
Why are parallel connection of power sources applied?
Eg. Generators in parallel
A
Paralleled if the required current exceeds the permitted load of a single power source (overload).
For this reason, generators in power plants are connected in parallel
6
Q
In a series circuit of generators, what happens to voltage and current?
A
Increases the voltage and current remains constant
