Electricity
Electrical circuits and current
| Term | Definition |
|---|---|
| Electricity | Energy in its electrical form (Eelect) |
| Electrons | A particle that carries energy though the circuit . It is part of an atom and has a negative charge |
| Conductors | These atoms have loosely bound electrons, the electrons can wander, conductors allow elections to pass though it |
| Insulator | Prevents or STOPS electricity from traveling through it |
| Battery | Stores Echem/converts Echem to Eelect |
| Current | Amount of charge (e-) that passes a point in the circuit every second |
| What does a multimeter do | It measures the amount amps and volts that are in a circuit |
| Units for current | Ampère = Amps = A |
| Resistor | A device that transforms Eelect into the flavor of energy you want |
| What is the symbol for a resistor in a circuit drawing? | ------/\/\/\/\/----- |
| What is the symbol for a battery in a circuit drawin? | ------| l------- (Big end is positive, small end is negative) |
| What is the symbol for a multimeter in a circuit drawing? | An A inside of a circle |
| Conventional current | flows from (+) end of battery to the (-) end |
| What is a proton? | A positively charged particle that makes up some of the nucleus |
| What is an electron? | A negatively charged particle that orbits around an atom, they carry Eelect throughout the circuit |
| Where do electrons come from? | They are already in the metal atoms of the conductors in the circuit |
| What is a Coulomb? | A unit of measurement for measuring the amount of electrons in a circuit, like how you count eggs in dozens, you count electrons in Coulombs |
| How many electrons are in 1 Coulomb? | 6.25 x 10^25 electrons |
| What does voltage measure? | Voltage measures the ENERGY POSSESSED by 1 COULOMB of electrons |
| Equation for voltage | Voltage = Joules/Current |
| Potential difference | (Delta)V is the difference of energy across the device |
| How does the resistance change as the electrons move through the circuit? | It doesn't |
| How do you change the resistance Ina circuit? | To change the resistance you must change the resistor material or geometry (diameter, circumference) |
| How does current change as it travels through the circuit? | It doesnt |
| Vtotal = ... | V1 + V2 + V3 + V4 .... |
| How long is the filament in a lightbulb? | 1 meter |
