Front

What is the symbol for a battery?

Back

The symbol for a battery is two parallel lines, one longer than the other.

Front

What is a circuit?

Back

A circuit is a closed path through which electrical current flows.

Front

What is a multiview sketch?

Back

A multiview sketch is a drawing that shows multiple views of an object, typically the front, top, and side.

Front

What is a voltage source?

Back

A voltage source is a device that provides electrical energy, such as a battery or power supply.

Front

What is a resistor?

Back

A resistor is a component that slows down or reduces the flow of electric current.

Front

What is an electrical current?

Back

An electrical current is the flow of electric charge, typically measured in amperes.

Front

What is a circuit diagram?

Back

A circuit diagram is a visual representation of an electrical circuit, showing the components and their connections.

Front

What is the purpose of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across the same voltage source.

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). Formula: V = I × R.
