### Charging

the temporary lighting of bulbs when a capacitor is connected to a circuit with a battery

### Plates

the conducting layers of the capacitor

### Discharging

the temporary lighting of bulbs with only a full capacitor in the circuit

### Schematic diagram

a circuit picture made with specialized symbols recognized by scientist and engineers

### Capacitor

3 layer device with 2 conducting plates with an in-between insulation layer and stores charge and energy

### Terminal

screw or wire attached to the capacitor plate that extends outside of it and lets the plate connect to the circuit

### Reset a capacitor

touch a wire simultaneously to both capacitor terminals to discharge it

### Energy

ability to make something happen

### Cell

another name for a battery

### series circuit

all of the moving charge passes through every resistor- every part of charge is resisted

### parallel circuit

the moving charge is split into different parts- each part passes through only one resistor; it will be resisted only once

### more in series

acts like single longer resistor which makes flow harder

### more in parallel

acts like single wider resistor which makes flow easier

### arrowtails

used in schematic diagrams to indicate the direction of charge motion in a circuit

### bulbrays or starbursts

represent how bright the bulb is- the more rays, the brighter

### standard

in a circuit, there are three batteries, 2 bulbs, and sometimes a capacitor

### conductors

objects that are good at allowing charge to flow easily

### insulators

objects that aren't good at allowing charge to flow easily

### Ohm

the unit that is used to measure electrical resistance

### example of resistance

an object that allows charge to flow freely has low resistance

### example of resistance 2

an object that slows the flow of charge has low resistance

### resistors

objects that allow charge to flow at a reduced rate

### resistance

something that some objects will have during an energy output that slows down the flow rate of charge

### current

flow rate of charge in a circuit

### series

the connection of bulbs in single file lines; has only one CCP

### Trunk wire

wires connected to the battery before charge flow splits into different branches

### branches

individual conducting paths which are side by side

### short circuit

parallel path which has little or no resistance compared to the rest of the circuit

### parallel

arrangement of bulbs in multiple side by side branches; has multiple conducting paths

### amp

unit used to measure flow rate

### standard circuit setup

a circuit that has a 3 cell battery and has 2 round bulbs in a series

### how to use a Genecon to see if a capacitor was charged

when the Genecon handle turns, it is discharging, which meant that it would have had to have been charged to discharge

### long bulbs

usually take longer to light than the round bulbs because they have larger filaments

### round bulbs

are bulbs that light up very bright and quick when charging goes on

### does charge stored in a capacitor depend on the bulb types through which they were charged

yes, because it takes longer to charge a capacitor through long bulbs than round bulbs

### how does the number of bulbs in a loop affect resistance

the more bulbs there are, the more resistance there is

### flow rate

it is different than speed because it tells how much charge passes through a point each second in a wire

### speed

speed is different than flow rate because it tells how fast the charge is moving

### air pressure

pushing effort of compressed air

### electric pressure

property of compressed charge that lets it push itself out of a conductor

### electric resistance

resistance of a material to the flow of an electric current through it

### circuit

path along which electrons can flow

### volt

unit used to measure electric pressure

### Ohm's Law

current= voltage/resistance
