15 cards from this deck
Graph of current vs voltage for a component
Resistor, filament lamp, diode
Current
Potential difference (voltage)
In series with component
In parallel across component
To change the voltage
To get negative values for complete picture
Current (III)
Potential difference (VVV)
Straight line through origin (ohmic)
Curved line (resistance increases as it heats)
Current only flows in one direction
Components heat up, changing resistance & affecting readings
Control current flow & prevent dangerous currents
