Series and Parallel Circuits general

Front

What is a series circuit?

Back

A circuit where components are connected end-to-end, so the current flows through each component in turn.

Front

What happens if one component fails in a series circuit?

Back

If one component fails, the entire circuit is broken and all components stop working.

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

What happens if one component fails in a parallel circuit?

Back

If one component fails, the other components can still operate because there are multiple paths for current.

Front

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

Back

R_total = R1 + R2 + R3 + ... + Rn, where R1, R2, R3, etc. are the resistances of each component.

Front

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

Back

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

Front

What is an ammeter used for?

Back

An ammeter is used to measure the current flowing through a circuit.

Front

What is a voltmeter used for?

Back

A voltmeter is used to measure the voltage across two points in a circuit.

Front

What is the unit of current?

Back

The unit of current is the ampere (A).

Front

What is the unit of voltage?

Back

The unit of voltage is the volt (V).
