Circuits & Electricity

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. If one component fails, the entire circuit is broken.

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, providing multiple paths for the current to flow. If one component fails, the others can still operate.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow. It has no breaks or interruptions.

Front

What is an open circuit?

Back

An open circuit is a broken electrical circuit where the current cannot flow due to a break or interruption in the path.

Front

What materials are considered good conductors of electricity?

Back

Good conductors of electricity include metals such as copper, aluminum, and silver, which allow electric current to flow easily.

Front

What is the role of a resistor in a circuit?

Back

A resistor is a component that resists the flow of electric current, creating a voltage drop and controlling the current in 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) of the conductor. It is expressed as V = I * R.

Front

What is the difference between voltage and current?

Back

Voltage is the electrical potential difference between two points in a circuit, while current is the flow of electric charge through the circuit.

Front

What is a circuit breaker?

Back

A circuit breaker is an automatic switch that stops the flow of current in a circuit when it detects an overload or short circuit, protecting the circuit from damage.

What is the function of a capacitor in a circuit?

Back

A capacitor stores electrical energy temporarily and releases it when needed, helping to smooth out fluctuations in voltage and current.
