current has multiple paths to follow, broken circuit may not stop electrical flow, voltage is same throughout each resistor, current adds for each

Ohm's law
Front
Ohm defined how current (amps), voltage (volts), and resistance (Ohms Ω) relate
Back
current
Front
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

voltage in circuits
Front
parallel: V=V1=V2=V3=...
(voltmeters only for voltage)
series: V=V1+V2+V3+...

V=IR
Front
Ohm's law equation, V=voltage of battery, I=current, R=resistance
