electrical circuits

Front

What is an open circuit?

Back

An open circuit is a circuit in which the path for current flow is broken, preventing electricity from flowing.

Front

What is the pathway for electric current in a circuit?

Back

The pathway for electric current in a circuit is typically through wires.

Front

How can we observe energy in a circuit?

Back

Energy in a circuit can be observed when components like light bulbs light up.

Front

What is a conductor?

Back

A conductor is an object that allows electric current to flow through it.

Front

What are the two main types of circuits?

Back

The two main types of circuits are series circuits and parallel circuits.

Front

What is a series circuit?

Back

A series circuit is a circuit in which components are connected end-to-end, so the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a circuit in which components are connected across common points or junctions, allowing current to flow through multiple paths.

Front

What happens to the total resistance in a series circuit?

Back

In a series circuit, the total resistance is the sum of the individual resistances of each component.

Front

What happens to the total resistance in a parallel circuit?

Back

In a parallel circuit, the total resistance is less than the smallest individual resistance and can be calculated using the formula 1/R_total = 1/R1 + 1/R2 + ... + 1/Rn.

Front

What is the role of a resistor in a circuit?

Back

A resistor is a component that resists the flow of electric current, thereby controlling the current and voltage in a circuit.
