Series 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.

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 series.

Front

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

Back

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

Front

What is the total current in a series circuit?

Back

The total current is the same through all components in a series circuit.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow.

Front

What is an open circuit?

Back

An open circuit is a broken circuit where current cannot flow due to a break in the path.

Front

What happens to the brightness of bulbs in a series circuit as more bulbs are added?

Back

The brightness of the bulbs decreases as more bulbs are added in series.

Front

What is the role of a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of current.

Front

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

Back

The symbol for a battery is two parallel lines, one longer (positive) and one shorter (negative).

Front

What is the effect of adding a resistor in series?

Back

Adding a resistor in series increases the total resistance and decreases the total current.
