Electricity and Circuits

Front

What type of circuit allows each component to be turned on and off separately?

Back

Front

Which material is NOT considered a conductor of electricity?

Back

Wood.

Front

What is the term for the measure of potential energy stored in a battery?

Back

Voltage.

Front

What device is used to prevent excessive current flow in a circuit?

Back

Fuse.

Front

Why can pennies be used to create a battery?

Back

Because they are conductors.

Front

What is the primary difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

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

Back

To limit the flow of electric current.

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, expressed as V = IR.

Front

What is the unit of electrical resistance?

Back

Ohm.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.
