A person who designs electrical systems for things like phones, computers, and machines may work in this field.
What is Electrical Engineering?
This type of material allows electricity to flow through it easily.
What is a Conductor?
This is the flow of electrically charged particles, such as electrons, and is measured in Amps.
What is Current?
This is electrical energy caused by the movement of charged particles such as electrons.
What is Electricity?
This force can attract or repel objects containing magnetic materials such as iron.
What is Magnetism?
This conductor is the point where electrons leave a device.
What is the Anode?
Copper wire is commonly used in electrical circuits because copper is this type of material.
What is a Conductor?
This is the "push" that causes electrical charges to move and is measured in Volts.
What is Voltage?
This provides a pathway for charged particles to travel through a circuit.
What is a Circuit?
This type of magnet gets its magnetic field from an electric current.
What is an Electromagnet?
This conductor is the point where electrons enter a device.
What is the Cathode?
This type of material does NOT allow electricity to flow through it easily.
What is an Insulator?
This part of a simple circuit provides the electrical energy needed to make the light bulb work.
What is the Battery?
Name the four main parts of the simple circuit we drew in class.
What are a battery, wires, switch, and light bulb?
You wrap a wire around an iron nail and connect the wire to a battery. What have you created?
What is an Electromagnet?
This electronic component limits the flow of electrons in a circuit.
What is a Resistor?
Rubber, plastic, and silicone are commonly used around electrical wires because they are this.
What are Insulators?
This is the opposition to the flow of electrical current and is measured in Ohms.
What is Electrical Resistance?
If a circuit has a battery and light bulb but there is a break in the pathway, the light bulb will not turn on because the circuit is ________.
What is open?
This part of a circuit can be opened or closed to control whether electricity flows.
What is a Switch?
This type of current flows in only one direction, such as the electricity supplied by a typical battery.
What is Direct Current (DC)?
You are making an electrical wire. Which would be the better material for the inside of the wire: copper or rubber? Explain why.
What is copper, because it is a conductor and allows electricity to flow?
A kink in a water hose makes it harder for water to flow. In an electrical circuit, this is similar to what?
What is Electrical Resistance?
A switch is opened (off) in a circuit. What happens to the flow of electricity and the light bulb?
What is the flow stops and the light bulb turns off?
This component is added to a circuit to slow down or limit the flow of electricity.
What is a Resistor?
