Study Notes
Ohm's Law
- 'E' in Ohm's law formula stands for Electromotive force
- Units for 'E' are volts
- If resistance increases, current decreases.
- If voltage increases, current increases.
Circuit Types
- Series Circuit: Current is the same through each resistor.
- Series Circuit: Voltage drop across each resistor adds up to the source voltage.
- Parallel Circuit: Voltage drop across each resistor is the same as the source voltage.
- Parallel Circuit: Current flow through each resistor depends on resistance.
- Power Law: If power increases, voltage increases if amperage stays the same.
