Make the light bulb light up with the battery by touching the bottom tip of the bulb to the positive or bumpy end of the battery. The bulb contains two wires extending into the inside of its base that create the circuit that lights the bulb. One stops at the side of the metal base a...
How to Generate Electricity: Hydroelectricity / Hydro Electric Power Hydroelectricity is the most common method of generating electricity.Wateris stored is ahigh damor an artificial or natural lake or reservoir. This water stored in a high place hasgravitational potential energy. Down this source of ...
begins to “break down” or conduct at a specific voltage, called its Zener voltage. Once it starts conducting, there is no stopping the current, so aresistor(R1 shown below) needs to limit the current to a safe value.
A printed circuit board has pre-designed copper tracks on a conducting sheet. The pre-defined tracks reduce the wiring thereby reducing the faults arising due to lose connections. One needs to simply place the components on the PCB and solder them. Different method to make PCB There are in a...
CAUTION: Diodes will dissipate a lot of heat so make sure they are mounted on a suitable heatsink. As we all know that a normal diode, like a 1N4007 drops 0.6 to 0.7 volts across it, when a DC is applied, means that many diodes put in series would drop the relevant amount of volta...

There’s a lot you can do with electric play dough! Here’s how to make it work: Take two small balls of conductive dough. Stick a wire from your battery pack into each ball. Place a LED into both balls of dough–the lights have a positive and negative wire, so if it doesn’t ...
An electric circuit diagram makes use of symbols in representing the components of a circuit. Also, they will show you ways of connecting a circuit as well as make it function. It is also useful in determining the current present in several parts of a circuit. The circuit diagram will also...
