Circuits

Front

What type of circuit is used in security alarms that turn on when the circuit is broken?

Back

Series circuit.

Front

What is the force that pushes electricity through a circuit?

Back

Voltage.

Front

What happens to the current and brightness of lights when more light bulbs are added to a series circuit?

Back

The current slows down and the lights dim lower.

Front

What kind of circuit is characterized by components connected end-to-end, so that current flows through each component in turn?

Back

Series circuit.

Front

What is the flow of electricity through a conductor called?

Back

Current.

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Ohm's Law: Voltage = Current x Resistance.

Front

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

Back

The total resistance increases.

Front

In a series circuit, if one component fails, what happens to the rest of the circuit?

Back

The entire circuit stops working.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected in a single path; in a parallel circuit, components are connected across multiple paths.

Front

What is the unit of measurement for electric current?

Back

Ampere (A).
