Front

What is a circuit board diagram?

Back

A circuit board diagram is a visual representation of an electronic circuit, showing the connections and components such as resistors, capacitors, and power sources.

Front

What type of wiring is commonly used in household electrical systems?

Back

Parallel wiring is commonly used in household electrical systems, allowing multiple devices to operate independently.

Front

What does a resistor do in an electrical circuit?

Back

A resistor limits the flow of electric current in a circuit, helping to control voltage and current levels.

Front

What are the two types of magnetic poles?

Back

The two types of magnetic poles are north and south poles.

Front

What is the function of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

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: V = I * R.

Front

What is the role of a switch in an electrical circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is an electric current?

Back

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

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected, characterized by the presence of magnetic poles.
