vocab
A complete path through which electricity flows.
what is an circuit
How does a conductor let electricity pass through?
A conductor has free-moving electrons that allow electricity to flow easily.
What is the function of an insulator?
An insulator prevents electric current from flowing in unwanted areas, keeping circuits safe
: Where do you find voltage in a battery-powered circuit?
Voltage is found between the positive and negative terminals of a battery.
How is current measured in a circuit?
Current is measured in amperes (A) using an ammeter.
A material that allows electricity to pass through it easily (e.g., copper, aluminum). ctor
what is a conductor
How does an insulator block electricity?
An insulator has tightly bound electrons that do not allow electricity to pass through.
What is the purpose of a circuit?
A circuit provides a path for electricity to flow and power devices.
Where would you place an insulator for safety?
Insulators are placed around wires, plugs, and circuit components to prevent shocks.
How do insulators keep us safe?
Insulators prevent electric shocks and short circuits by stopping current from flowing in the wrong places.
A material that does not allow electricity to flow through it easily (e.g., rubber, plastic).
what is an insulator
How does a circuit allow electricity to flow?
A circuit allows electricity to flow by providing a continuous, closed path for current to trave
What does voltage do in an electrical system?
Voltage pushes the electrical current through the circuit to power devices.
Where does a circuit start and end?
A circuit starts at the power source (battery or outlet) and ends back at the power source.
How are conductors used in wiring and electronics?
Conductors are used in electrical wires, circuit boards, and power lines.
The flow of electric charge through a circuit, measured in amperes (A).
what is a current
How does current move through a circuit?
current moves from the power source, through conductors and components, and back to the source.
What does electric current do?
Electric current delivers energy to components like light bulbs, motors, and resistors.
Where does current flow in a series vs. parallel circuit?
In a series circuit, current flows in one loop; in a parallel circuit, it flows through multiple branches.
How do we measure voltage in a circuit?
: Voltage is measured in volts (V) using a voltmeter.
The electrical force that pushes the current through a circuit, measured in volts (V).
what is voltage?
How does voltage push current through a circuit?
Voltage creates an electrical force that moves electrons through the circuit.
What is the role of a conductor in a circuit?
A conductor helps electricity flow efficiently from one part of the circuit to another.
Where are conductors commonly found in a circuit?
Conductors are found in wires, circuit boards, and inside electronic devices.
How do we use circuits in everyday life?
Circuits power household appliances, phones, computers, and vehicles.
