Series and Parallel Circuits

Front

What is a series circuit?

Back

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

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

Back

The total resistance increases as more resistors are added in a series circuit.

Front

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

Back

The total resistance decreases as more resistors are added in a parallel circuit.

Front

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

Back

RT = R1 + R2 + R3 + ... + Rn, where R1, R2, R3, ..., Rn are the resistances of the individual components.

Front

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

Back

1/RT = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn, where R1, R2, R3, ..., Rn are the resistances of the individual components.

Front

What is the effect of removing one component in a series circuit?

Back

Removing one component in a series circuit causes the entire circuit to stop working.

Front

What is the effect of removing one component in a parallel circuit?

Back

Removing one component in a parallel circuit does not affect the operation of the other components; they will continue to work.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A).

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts (V).
