Flashcards
Current Electricity
Cards in this deck (11)
- 1What is electrical charge?The flow of electrons/current
- 2What is potential difference?Energy transferred per coulomb of charge passing through a component
- 3Give the unit for chargeCoulombs, C
- 4Give the unit for powerWatts, W
- 5Give the unit for currentAmps, A
- 6Give the unit for resistanceOhms, Ω
- 7How is potential difference shown in series and parallel circuits?Series:
Potential difference is shared between components
Parallel:
Potential difference is the same through each component - 8How is current shown in series and parallel circuits?Series:
Current is the same throughout the circuit
Parallel:
Current is different in different branches - 9Why does a current-potential difference graph for a diode stay at 0 for negative readings?Diodes only allow current to flow in one direction
- 10Describe a current-potential difference graph for a resistorA straight, linear line for both positive and negative readings
- 11Describe a current-potential difference graph for a lampA slanted S shape
