Electricity Unit Review (LT's 1-5 only)

Front

What is the law of charge conservation?

Back

The law of charge conservation states that the total charge in an isolated system remains constant; charge can neither be created nor destroyed, only transferred.

Front

How do objects become charged?

Back

Objects become charged through the transfer of electrons between objects.

Front

What happens to the total current in a parallel circuit when another branch is added?

Back

Adding another branch to a parallel circuit increases the total current in the circuit.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break in the path for current to flow; it is considered 'off'.

Front

What is the unit of measurement for resistance?

Back

The unit of measurement for resistance is Ohm (Ω).

Front

What are the two types of electrical forces?

Back

Electrical forces can attract and repel charged objects.

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 the role of a resistor in a circuit?

Back

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

Front

What is voltage?

Back

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

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A).
