circuits
current
current is the rate of the flow of charge
current is measured with an ammeter
Charge = Current * Time Q=IT
voltage
energy transferred per coulomb
voltage is also called potential difference
voltage measured with a voltmeter
Energy transferred = Voltage * charge E = VQ
series
Current is the same through each component
Voltage across the circuit must add up to voltage of battery
Removing a component turns off others
parralel
voltage is the same throughout and the same as the battery
Total current is shared between components in parralel
removing one component doesn't turn off others
resistance
Voltage = Resistance * Current V= IR
