Question | Answer |
What do you call the careful and exact control of very small currents | Electronics |
What do you call a component that allows current to flow in one direction only | Diode |
When the positive terminal of a battery is connected to the positive end of a diode, it allows current to flow, what direction is this said to be? | Forward biased |
When the positive terminal of a battery is connected to the negative end of a diode, it does not allow current to flow, what direction is this said to be? | Reverse biased |
True or false. A diode can be used to change alternating current into direct current | True |
What do you call a diode that gives out light when current flows through it | Light Emitting Diode (LED) |
Where would you find LEDs | indicator lights on many electronic devices |
What are the advantages of LEDs | Use less current, cheap, reliable and long lasting |
What do you call a resistor whose resistance depends on light | Light Dependent Resistor (LDR) |
Where would you find LDRs | Controls street lighting |
