Waves
The highest point of a wave
Crest
When two objects are touching, what type of heat transfer can occur?
Counduction
If one load stops working in a series circuit what happens to any other loads in the circuit?
They also stop working.
What is heat
A form of energy
What is a load
What is a source
What is wavelength?
The distance from one crest to another, or from one trough to another
When you are warming your hands beside a campfire, heat is being transferred through _________.
Radiation
In a parallel circuit electricity has ______ path(s) to follow
Multiple
If you connect the wires of an electric circuit to a piece of jewelry why would the light bulb in the circuit still turn on?
Because the jewelry is made of something that can conduct electricity.
This means to be at right angles
Perpendicular
This word means to move or swing back and forth
oscillating
List 3 types of materials that are good conductors
Any types of metal - aluminum, steel, iron
What is the role of a load in an electric circuit?
The load is the part of the circuit that receives electrical energy and can be turned on.
A. Electric generator
It lets heat pass through easily
A conductor
This is the word we use to measure frequency
What is hertz
Is an electric blanket an insulator or a conductor? Explain.
It could be both. It is a conductor because the heat from the electric blanket is touching your skin, and it is an insulator because it traps your body heat underneath the blanket.
Explain how a switch works in an electrical circuit.
When the switch is on the circuit is closed so electricity can flow. When the switch is off the circuit is open so electricity cannot flow.
When heat is removed from an object
Cooling
electricity can flow on multiple paths
parrallel circuit
This is how a surface wave forms
What is when a transverse & longitudinal wave combine
Explain the difference between convection and radiation.
Convection transfers heat through air or gas, radiation transfers heat through electromagnetic waves
Why do electricians use wire that is coated in plastic when they are making new circuits?
This is because the wire can be dangerous to handle and can shock humans if they handle it when the circuit is on. The plastic coating helps to protect the electricians and us!
What is faster: light waves or sound waves
What is light waves
This is where the particles of a longitudinal wave are crowded together
What is compression
