Facts
- Current=the rate at which charge flows
- I=current
- R=V/I
- R=Resistance (like electrical friction) the unit is omega
- Sound=pushing air particle
- V=Voltage (energy per unit of charge)
- Different meters have different resistance
- Ammeter=measure the amp
- When positive and positive are working together they use less cells
