Electric and Magnetic Forces Review

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where multiple devices are connected along a single pathway, so the same current flows through all devices.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where multiple devices are connected across common points or junctions, allowing current to flow through multiple pathways.

Front

What are the three essential components of all circuits?

Back

All circuits have a device/load, a power source, and conducting material (wire).

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electric current by breaking or connecting pathways.

Front

What is a generator?

Back

A generator is an electromagnetic device that converts mechanical energy into electrical energy.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the difference between an open circuit and a closed circuit?

Back

An open circuit has a break in the pathway, preventing current from flowing, while a closed circuit has a complete pathway allowing current to flow.

Front

What is electrical current?

Back

Electrical current is the flow of electric charge, typically measured in amperes (A).

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V).

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω).
