This 9VDC source using zener and transistor can be used to power circuits or electronic devices that would normally use a 9 volt battery, saving us the cost of the battery while being used at home.
The Power Supply block Diagram Many electronic circuits need a direct current (DC) voltage source, but what we commonly find are voltage sources of alternating current (AC). In order to achieve a direct current voltage source, the alternating current input must follow a conversion process like the one shown in the chart below. The chart shows the operation of […]
What is Voltage? Voltage is the electrical potential difference caused by the accumulation of electric charges on a point, or a material. If we remove electrons from a material, its total electric charge will be positive. Remember that we are removing electrons, which are negatively charged, from a neutral atom (which has no charge). This causes the atom is no […]
