series circuit

Front

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

Back

ammeter symbol

Front

Back

ammeter

Front

measures current (Amps)

Back

P=I²R=V²/R=IV

Front

power equation, P=power(watts)=energy/time, I=current (Amps), R=resistance (Ω), V=voltage (Volts)

Back

voltmeter symbol

Front

Back

resistance

Front

impedes current, uses energy (Ohms Ω)

Back

lamp symbol

Front

Back

current in circuits

Front

parallel: I=I1+I2+I3+... (increases w/ additional resistors) series: I=I1=I2=I3=... (decreases w/ additional resistors, ammeters only)

Back

battery symbol

Front

Back

parallel circuits

Front

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

Back

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

Back

battery

Front

voltage (source) (Volts)

Back

voltage in circuits

Front

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

Back

V=IR

Front

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

Back

resistance in circuits

Front

parallel: 1/R=1/R1+1/R2+1/R3+... (decreases w/additional resistors) series: R=R1+R2+R3+... (increases w/ additional resistors)

Back

voltmeter

Front

measures voltage (Volts)
