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.

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, allowing multiple paths for the current to flow.

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 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 parallel.

How does voltage behave in a series circuit?

Back

In a series circuit, the total voltage is divided among the components, and the sum of the voltages across each component equals the total voltage.

Front

How does voltage behave in a parallel circuit?

Back

In a parallel circuit, the voltage across each component is the same and equals the total voltage.

Front

How does current behave in a series circuit?

Back

In a series circuit, the same current flows through all components.

Front

How does current behave in a parallel circuit?

Back

In a parallel circuit, the total current is the sum of the currents through each parallel branch.

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): V = I × R.

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

Back

The total resistance (R_total) in a series circuit is the sum of the individual resistances: R_total = R1 + R2 + R3 + ...
