Series and Parallel Circuits

Front

What is a series circuit?

Back

A circuit where components are connected in a single path, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

In a parallel circuit, what happens if one component fails?

Back

The other components continue to function because there are multiple paths for current.

Front

What is the voltage across components in a parallel circuit?

Back

The voltage drop across each component is the same.

Front

What is the total current in a parallel circuit?

Back

The total current is the sum of the currents through each parallel branch.

Front

What is the formula for total resistance in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current.

Front

What does a battery do in a circuit?

Back

A battery provides the electrical energy needed to drive the current through the circuit.

Front

What is the symbol for a switch in a circuit diagram?

Back

A switch is represented by a break in the line with a connecting line that can close the gap.

Front

What is power dissipation in a circuit?

Back

Power dissipation refers to the conversion of electrical energy into heat energy in circuit components.
