Kirchhoff's First Law
- The sum of the currents entering
any junction is always equal to the
sum of the currents leaving the
junction.
- If they don't add up: ammeters may
have bit of resistance, rounding errors
- Electron flow: negative to positive
Conventional current: positive to negative
- Conventional - incorrect
- Measuring current: flow of electrons
- Voltage = resistance x current
- Higher the resistance,
smaller the current
- Adding ammeter changes
resistance - changes current
- Ideal ammeter has 0 resistance
- Ammeters added
in series
