T or F. It is safe to push something into an electrical outlet as long as you do it with your eyes closed
False. It is not safe, or funny, to push things into electrical outlets. You could be seriously injured or killed
The three types of subatomic particles
Protons, neutrons and electrons
A closed path that allows electric current to flow
Electric circuit
An average AA battery is this many volts (the ones we used yesterday). Hint: Marc said it in the Q & A
1.5 V
DC means
Direct current
T or F. Water is an excellent insulator
False, it is an excellent conductor
The subatomic particle that has no charge
Neutron
The subatomic particle that has positive charge
Proton
This device converts sunlight into electricity by using prisms (called photovoltaic (PV) cells) that produce excited electrons when exposed to light
Solar panel
AC means
Alternating current
T or F. If you grab on to something with an electric charge and receive an electric shock, you might not be able to let go
True. The electric charge can confuse the electrical impulses in your muscles
A substance or device that readily transmits electrons
Conductor
A substance or device that does not readily share electrons
Insulator
A household electrical current carries electricity at how many volts?
120V
This American inventor championed DC current
Thomas Edison
T or F. Increased voltage means decreased risk to human safety
False. Increased voltage means increased risk to human safety
"A container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power"
Battery
A fundamental law in electrical engineering that describes the relationship between current (I), voltage (U), and resistance (R)
Ohm’s Law
In order to become an electrician in Manitoba, you need to complete an __________________, which is a mixture of work and school
Apprenticeship
Is household power AC or DC?
AC
T or F: Electricity has the ability to jump through the air to find a path to ground
True! This is called arcing. Always keep yourself and your tools at least 4 meters away from power lines
