Circuits Review

Front

What is required for a battery to function in a circuit?

Back

The battery needs to form a complete circuit that starts with one metal post and ends with the other metal post.

Front

What happens if a lightbulb is not part of a circuit?

Back

The lightbulb is not a part of a complete circuit, and therefore it will not light up.

Front

What is one form of energy that can be produced in a circuit?

Back

Heat.

Front

How do you connect two batteries in series?

Back

Turning one battery so that its positive end connects to the other battery's negative end.

Front

What is the effect of closing switches in a circuit?

Back

Closing Switches 2 and 3 while leaving Switch 1 open allows current to flow through the circuit.

Front

What is a complete circuit?

Back

A complete circuit is a closed loop that allows electric current to flow from the power source, through the components, and back to the power source.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of current in a circuit by opening (stopping current) or closing (allowing current) 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 happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases as more resistors are added in series.

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): V = I * R.
