It might be a generator, wind turbine or solar panels. There are plenty of ways to provide yourself with a reliable source of post-disaster electricity. There are all sorts of reasons why your power supply might not work.

This e-book covers the Light Emitting Diode. It has changed from a dimly-glowing indicator to one that is too-bright to look at. However it is entirely different to a "globe.

A LED is more efficient, produces less heat and must be "driven" correctly to prevent it being damaged. A "Natural" or "Characteristic" voltage develops across a LED when it is correctly connected in a circuit with a current-limiting resistor to allow a current between 1mA and 20mA. This voltage is shown in the table above and we normally use the lower value for each colour.

However the table shows the voltage varies quite a lot and this depends on the actual crystalline construction of the crystal and the way it is manufactured. The voltage across a LED depends on the manufacturer, the intensity of the colour and the actual colour.

You must test the LED s you are using. The voltage across some LEDs increases by mV 0. If you are using a 12v supply, you cannot should not put 4 white LEDs in series as the "characteristic voltage will be 3. You will need to remove one LED and fit a resistor to get the brightness you require.

The LED in the second diagram is damaged because it requires 1. A resistor is needed to limit the current to about 25mA and also the voltage to 1. The fourth diagram is the circuit for layout 3 showing the symbol for the LED, resistor and battery and how the three are connected.

The LED in the fifth diagram does not work because it is around the wrong way. A LED works like this: A LED and resistor are placed in series and connected to a voltage.

As the voltage rises from 0v, nothing happens until the voltage reaches about 1. At this voltage a red LED just starts to glow. As the voltage increases, the voltage across the LED remains at 1. We now turn our attention to the current though the LED.

As the current increases to 5mA, 10mA, 15mA, 20mA the brightness will increase and at 25mA, it will be a maximum. Increasing the supply voltage will simply change the colour of the LED slightly but the crystal inside the LED will start to overheat and this will reduce the life considerably.

In the diagram below we see a LED on a 3v supply, 9v supply and 12v supply. The current-limiting resistors are different and the first circuit takes 6mA, the second takes 15mA and the third takes 31mA. But the voltage across the red LED is the same in all cases.The (V2) Multifunction Wireless Controlled 12 LED Hanging Battery Terminal For Lanterns - White illuminates all of our lanterns from 12" to 36".

Test leads are considered to be an integral part of electrical measurement, for example connecting your digital multimeter to the unit under test.

If the test leads are in poor condition this can lead to inaccurate readings and could result in a health and safety concern if .
