Circuits

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What are the two main types of circuits?

Back

The two main types of circuits are series circuits and parallel circuits.

Front

In a series circuit, what happens if one component fails?

Back

If one component fails in a series circuit, the entire circuit is broken and all components stop working.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where multiple paths exist for current to flow, so if one path is broken, current can still flow through other paths.

Front

What is the role of a conductor in a circuit?

Back

A conductor allows electric current to flow through it, typically made of materials like copper or aluminum.

Front

What is the function of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit, providing control over the amount of current.

Front

What is the difference between voltage and current?

Back

Voltage is the electrical potential difference between two points, while current is the flow of electric charge through a 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): V = I * R.

Front

What is a complete circuit?

Back

A complete circuit is one that has no breaks, allowing current to flow uninterrupted from the power source, through the load, and back.

Front

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

Back

The brightness of bulbs in a series circuit decreases as more bulbs are added because the total resistance increases, reducing the current.
