What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end, so that the same current flows through all components.

Front

What is a parallel circuit?

Back

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

Front

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

Back

The total current decreases because the total resistance increases.

Front

What happens to the voltage in a series circuit?

Back

The total voltage is divided among the components, with each component receiving a portion of the total voltage.

Front

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

Back

The total current increases because additional paths for current flow are created.

Front

What is the main difference between series and parallel circuits?

Back

In a series circuit, the same current flows through all components, while in a parallel circuit, the voltage across each component is the same, and the total current is the sum of the currents through each path.

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) of the conductor. It is expressed as V = I × R.

Front

What is a resistor?

Back

A resistor is a component in an electrical circuit that resists the flow of electric current, creating a voltage drop.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to drive the current through the circuit.

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two points in a circuit, allowing excessive current to flow, which can cause damage.
