Capacitors: Construction, Charging & Discharging

1. Capacitors: Construction, Charging & Discharging

Electrical circuits have several components, each of which must be understood for the system to work. We're going to check out capacitors in this lesson and see how they can be used to control an electric current.

Series & Parallel Capacitors

2. Series & Parallel Capacitors

A capacitor is used to store electrical energy in a circuit. In this lesson, learn how to calculate the equivalent capacitance of circuits containing series and parallel capacitors.

Resistor-Capacitor (RC) Circuits: Practice Problems

3. Resistor-Capacitor (RC) Circuits: Practice Problems

After watching this video, you will be able to calculate or deduce the current and voltage in the components of an RC circuit at the start of the charging process and when the capacitor is fully charged. A short quiz will follow.

R-L-C Series Circuits

4. R-L-C Series Circuits

After watching this lesson, you will be able to explain what an RLC series circuit is and use related equations to solve simple problems. A short quiz will follow.

Alternating Current Power Calculations

5. Alternating Current Power Calculations

After watching this lesson, you will be able to explain the difference between AC and DC circuits and calculate AC current, AC voltage and AC power using both rms values and peak values. A short quiz will follow.

Impedance in Alternating Current Circuits

6. Impedance in Alternating Current Circuits

In this lesson, you will learn about topics that include the difference between DC and AC circuits, the use of rms values, definitions of impedance and reactance, and calculations involving the reactance of capacitors and inductors.
