| 9647969708 | current | flow of positive charges in theory but flow of negative charges in real life, a river of electrical energy that moves through a wire, must have a closed continuous loop to work, number of charges that travel per second (Amps) I=q/t | 0 | |
| 9647969709 | battery | voltage (source) (Volts) | 1 | |
| 9647969710 | resistance | impedes current, uses energy (Ohms Ω) | 2 | |
| 9647969711 | ammeter | measures current (Amps) | 3 | |
| 9647969712 | voltmeter | measures voltage (Volts) | 4 | |

| 9647969714 | Ohm's law | Ohm defined how current (amps), voltage (volts), and resistance (Ohms Ω) relate | 9 | |
| 9647969715 | V=IR | Ohm's law equation, V=voltage of battery, I=current, R=resistance | 10 | |

| 9647969717 | parallel circuits | current has multiple paths to follow, broken circuit may not stop electrical flow, voltage is same throughout each resistor, current adds for each | 12 | |
| 9647969718 | series circuit | current has only one path to follow, broken circuit stops all flow of electricity, current is the same through each resistor, voltage adds for each | 13 | |
| 9647969719 | voltage in circuits | parallel: V=V1=V2=V3=... (voltmeters only for voltage) series: V=V1+V2+V3+... | 14 | |
| 9647969720 | current in circuits | parallel: I=I1+I2+I3+... (increases w/ additional resistors) series: I=I1=I2=I3=... (decreases w/ additional resistors, ammeters only) | 15 | |
| 9647969721 | resistance in circuits | parallel: 1/R=1/R1+1/R2+1/R3+... (decreases w/additional resistors) series: R=R1+R2+R3+... (increases w/ additional resistors) | 16 |
