Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

4. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Electric motors are used for converting electrical energy to mechanical energy, while generators are used for converting mechanical energy to electrical energy. Learn about electromagnetic induction, and the role of alternating and direct currents in the conversion.

Parallel Circuits: Definition & Concepts

5. Parallel Circuits: Definition & Concepts

A parallel circuit possesses different branches and paths where the current can flow. Understand the definition of a parallel circuit, and explore relevant concepts such as the pathways and resistance in this type of circuit, as well as Ohm's law.

Series Circuits: Definition & Concepts

6. Series Circuits: Definition & Concepts

A series circuit is a circuit that has only one path in which current can flow, going through each component. Learn about circuit pathways and the concept behind a single pathway, explore the definition of a series circuit, and understand the relation of resistance and voltage to the current in a series circuit.

What is Electric Power?

7. What is Electric Power?

Electric power and its ability to measure energy in watts has become something that technical and non-technical people can understand quite easily. This lesson considers electric power, watts, current, voltage, resistance, and all of these variables' relation to each other.

What is Electric Current? - Definition, Unit & Types

8. What is Electric Current? - Definition, Unit & Types

Electrical current involves the flow of charged particles, or electrons, and it is an integral part of electricity. In this lesson, we will dive into the definition of current, as well as the unit and types to understand just how electricity moves.

Electrical Resistance: Definition, Unit & Variables

9. Electrical Resistance: Definition, Unit & Variables

Electrical resistance refers to the force that impedes electrons in an electrical current flowing through a conductor. Explore the causes of electrical resistance, the various factors that can affect the resistance of different objects, as well as the practical applications of objects with high resistance.

Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

10. Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

Ohm's Law describes the relationship between voltage, current, and resistance. Learn about Ohm's Law and understand this relationship, including its importance. Use the Ohm's Law equation to calculate the values of voltage, current, and resistance.

Energy Transfers in Circuits: Equations & Examples

11. Energy Transfers in Circuits: Equations & Examples
