Series and Parallel Circuits/Electric Current

Front

What happens in a parallel circuit if one connection is broken?

Back

In a parallel circuit, if one connection is broken, the other connections continue to work.

Front

What type of circuit has multiple pathways for current to follow?

Back

Parallel circuit.

Front

What is the symbol for a battery in circuit diagrams?

Back

The symbol for a battery is two parallel lines, one longer than the other.

Front

How many paths does a series circuit have for electric current?

Back

A series circuit has one path for electric current.

Front

What is the main difference between series and parallel circuits?

Back

In a series circuit, all components are connected in a single path, while in a parallel circuit, components are connected across multiple paths.

Front

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

Back

The total resistance increases when 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 when more resistors are added in a parallel circuit.

Front

What is electric current measured in?

Back

Electric current is measured in Amperes (A).

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit.

Front

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

Back

Total resistance (R_total) = R1 + R2 + R3 + ... (sum of all resistances).
