Electricity and Circuits

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, providing a single path for current to flow.

Front

What is a parallel circuit?

Back

A parallel circuit is an electrical circuit in which components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current, typically metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber, glass, or wood.

Front

What is the purpose of a fuse in a circuit?

Back

A fuse is a safety device that prevents excessive current from flowing through a circuit by melting and breaking the circuit when the current exceeds a certain level.

Front

What are circuit boards?

Back

Circuit boards are flat boards that hold and connect electronic components, allowing for the organization and functionality of electronic devices.

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor, expressed as V = I * R.

Front

What is the difference between AC and DC current?

Back

AC (Alternating Current) is an electric current that reverses direction periodically, while DC (Direct Current) flows in one direction only.

Front

What is a short circuit?

Back

A short circuit occurs when there is an unintended path for current to flow, often leading to excessive current that can cause damage or fire.

Front

What is a voltmeter used for?

Back

A voltmeter is an instrument used to measure the voltage across two points in an electrical circuit.
