Question 1 of 10
Which type of electrical source provides a constant voltage across its terminals?
A voltage source, by definition, maintains a constant voltage regardless of the current drawn from it.
Question 2 of 10
What is the key characteristic of an ideal voltage source?
An ideal voltage source has no internal resistance, allowing it to maintain a constant voltage without any voltage drop.
Question 3 of 10
What is the unit of measurement for voltage?
Voltage is measured in Volts (V), representing the electrical potential difference.
Question 4 of 10
Which of the following is an example of a voltage source?
Generators provide a constant voltage output and are a standard example.
Question 5 of 10
What is the key characteristic of an ideal current source?
An ideal current source has infinite internal resistance to maintain constant current.
Question 6 of 10
What is the unit of measurement for current?
Current is measured in Amperes (A), which is the flow of electric charge.
Question 7 of 10
Which type of source provides a constant current regardless of the voltage across its terminals?
A current source is designed to deliver a constant current.
Question 8 of 10
In a practical voltage source, what happens to the voltage as the load current increases?
Due to internal resistance, the voltage drops as the load current increases.
Question 9 of 10
What is the internal resistance configuration of a voltage source?
The internal resistance of a voltage source is in series with the voltage source.
Question 10 of 10
Which of the following is an example of a current source?
Photovoltaic cells approximate the behavior of a current source.
