Unit 3 Notes
- 1. Electricity
- 17. Electric Current I = q/t
- 20. Potential Difference V = Ed Unit 3 –Electricity
- 24. Resistance Unit 3 –Electricity
- 27. Ohm’s Law Unit 3 –Electricity
- 30. Example In any circuit, the higher the voltage, the higher the current will be. Conversely, the lower the voltage, the lower the current will be. This assumes that the resistance remains constant. However current is also determined by resistance. Resistance is the opposition to current flow. So, assuming that voltage is constant, the higher the resistance is the lower the current will be. Also, the lower the resistance the higher the current will be. Unit 3 –Electricity
