Capacitors Flashcard

Front

What is a capacitor?

Back

A capacitor is an electronic component that stores electrical energy in an electric field, used in various applications such as filtering, timing, and energy storage.

Front

What is a dielectric material?

Back

A dielectric material is an insulating substance that can be polarized by an electric field, commonly used in capacitors to increase their capacitance.

Front

Which material is commonly used as a dielectric in capacitors?

Back

Mica is commonly used as a dielectric in capacitors due to its excellent insulating properties.

Front

What is voltage in a circuit?

Back

Voltage, also known as potential difference, is the measure of electric potential energy per unit charge between two points in a circuit.

Front

What happens to resistance when a resistor is wider?

Back

A wider resistor will have less resistance compared to a narrower one.

Front

What is the relationship between voltage, current, and resistance?

Front

What is the unit of capacitance?

Back

The unit of capacitance is the Farad (F), which measures the ability of a capacitor to store charge.

Front

What is the effect of connecting capacitors in series?

Back

Front

What does a resistor do in a circuit?

Back

A resistor limits the flow of electric current in a circuit, creating a voltage drop.
