-The current displays how many coulombs flow every second
-Ammeters measure the flow of current, and can be placed anywhere in the circuit. Measured in amps A
-The sum of potential differences (voltage) of circuit components makes the potential difference across the power supply of circuit components. Measured in volts V
-Voltmeters measure the potential difference and are placed at either end of the cell/component
- Power = Voltage x Current
- Resistance = Voltage/Current
- In a series circuit…
