Voltage and Current Sources Quiz

Which of the following best describes an ideal voltage source?

• A source with infinite current capacity and zero voltage drop.

• A source that maintains a constant current regardless of the load.

• A source that maintains a constant voltage regardless of the load.

• A practical source used in real-world applications.

What distinguishes a non-ideal current source from an ideal one?

• It provides infinite current.

• Its output current varies with load voltage.

• It maintains constant voltage.

• It has zero internal resistance.

A sinusoidal waveform differs from a non-sinusoidal waveform because:

• It contains only odd harmonics.

• It is always triangular.

• It has a single, smooth periodic shape.

• It is non-repetitive.

Which instrument is best suited for displaying and analyzing waveforms?

• Ammeter

• Voltmeter

• Wattmeter

• CRO (Cathode Ray Oscilloscope)

What is the primary function of a digital multimeter?

• Measure frequency and phase

• Display waveforms graphically

• Measure voltage, current, and resistance

• Store energy for later use
