Circuit Diagrams

Front

Why is copper commonly used for electrical wiring?

Back

Copper is used for electrical wiring because it is an excellent conductor of electricity.

Front

Define electric current.

Back

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

Front

What is the role of an energy source in a circuit?

Back

An energy source provides the necessary power for the circuit to function.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected alongside each other, providing multiple paths for current to flow.

Front

Identify the symbol for a bulb in a circuit diagram.

Back

The symbol for a bulb is typically represented as a circle with a cross inside it.

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 happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit is broken and all components stop working.

Front

What is the function of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit.

Front

Explain the concept of voltage.

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor.
