What Component Graph is this? |
Resistor-Current increases in proportion to voltage |
|
|
What Component Graph Is This?
|
Bulb-As voltage increases the bulb gets hotter and resistance increases |
|
|
What component graph is this? |
Diode-a diode only lets current go in one direction and it has a very high resistance in the other direction |
|
|
What does a resistor do? |
It slows down the current in a circuit |
|
|
What does a bulb do? |
Lights up when electrons pass through |
|
|
What does a diode do? |
Forces current to flow in 1 direction? |
|
|
Resistance formula |
Resistance=Voltage/Current |
|
|
Current formula |
Current=charge/time |
