Circuit Types

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn. If one component fails, the entire circuit is broken.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which components are connected across common points or junctions, providing multiple paths for the current. If one component fails, the others can still function.

What is the main advantage of a parallel circuit?

Back

The main advantage of a parallel circuit is that all components receive the same voltage as the source, ensuring consistent brightness in bulbs or equal performance in devices.

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 all components. R_total = R1 + R2 + R3 + ...

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. The formula is 1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

How many types of circuits are there?

Back

There are two main types of circuits: series circuits and parallel circuits.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break in the path for current to flow. No current flows in an open circuit.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit through which current can flow. All components are connected, allowing electricity to pass.

Front

What is the effect of adding more resistors in series?

Back

Adding more resistors in series increases the total resistance, which decreases the overall current in the circuit.

Front

What is the effect of adding more resistors in parallel?

Back

Adding more resistors in parallel decreases the total resistance, which increases the overall current in the circuit.
