Current in Series and Parallel Circuits

Front

What is the definition of 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.

Front

What is the definition of a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, allowing multiple paths for the current to flow.

Front

What happens to the total current in a parallel circuit at a junction?

Back

The total current into a junction equals the total current out of a junction.

Front

What is the relationship between voltage and branches in a parallel circuit?

Back

The voltage is the same in all branches of a parallel circuit.

Front

What material is commonly used for electrical pathways in circuits?

Back

Metal is commonly used for electrical pathways in circuits.

Front

What is the effect of adding more resistors in series?

Back

Adding more resistors in series increases the total resistance of the circuit.

Front

What is the effect of adding more resistors in parallel?

Back

Adding more resistors in parallel decreases the total resistance of the circuit.

Front

How does current behave in a series circuit?

Back

The current is the same at all points in a series circuit.

Front

How does current behave in a parallel circuit?

Back

The total current is divided among the branches in a parallel circuit.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = I × R.
