Question 1 of 10
Which type of electrical source provides a constant voltage regardless of the current delivered?
A voltage source, by definition, maintains a constant voltage output.
Question 2 of 10
What is the key characteristic of an ideal voltage source in terms of internal resistance?
An ideal voltage source has zero internal resistance, implying no voltage drop within the source itself.
Question 3 of 10
What happens to the output voltage of a practical voltage source as the load current increases?
Due to internal resistance, a practical voltage source experiences a voltage drop as load current increases, hence the output voltage decreases.
Question 4 of 10
Which type of electrical source provides a constant current regardless of the voltage across it?
A current source provides constant current output, independent of the voltage developed across its terminals.
Question 5 of 10
What is the internal resistance of an ideal current source?
An ideal current source has infinite internal resistance to maintain a constant current flow.
Question 6 of 10
In a practical current source, what happens to the output current as the load increases?
In a practical current source, the current decreases as the load increases due to high internal resistance.
Question 7 of 10
Where is the internal resistance of a voltage source located?
The internal resistance of a voltage source is in series with the source voltage.
Question 8 of 10
Where is the internal resistance of a current source located?
The internal resistance of a current source is in parallel with the source.
Question 9 of 10
What happens to the total voltage of voltage sources if connected in series?
Voltage sources in series add their voltages.
Question 10 of 10
Which of the following is an example of a current source?
Photovoltaic cells act as a current source. Batteries and Generators are voltage sources.
