What is the primary purpose of a voltage regulator in an electronic circuit?

To maintain a constant output voltage

What effect does increasing the frequency of an AC signal have on the reactance of an inductor?

Increases the reactance

What is the relationship between voltage, current, and resistance in an electronic circuit?

Voltage is proportional to current times resistance, or V = IR

What is the main function of an inductor in an electronic circuit?

To store and release electrical energy

In a series-parallel circuit, how is the total resistance calculated?

By calculating resistances separately for series and parallel sections, then combining the results

In a transformer, what happens if the secondary coil has more turns than the primary coil?

The output voltage is greater than the input voltage

What is the primary role of the emitter in a Bipolar Junction Transistor (BJT)?

To emit electrons or holes

What is the formula for calculating electrical power?

P = V²/R

Which type of diode is commonly used for voltage regulation?
