In addition to reading this instructable it may be a good idea for you to read my other instructable "electronics components and what they do" to get a good understanding of what you are doing when building a project.

The operation of the control loop in a typical linear regulator will be detailed using the simplified schematic diagram in Figure 2 (the function of the control loop is similar in all of the linear regulator types).

## Using A Voltmeter To Test Current

Examples of electronic output devices include computer monitors, LCD alphanumeric panels (as on a calculator), small lamps or light-emitting diodes (LED), etc. Digilent boards include different output devices, but all of them include some number of individual LED, and seven-segment LED displays that can display the digits 0-9 in each digit position (each segment in the seven-segment display contains a single LED). LED are two-terminal semiconductor devices that conduct current in only one direction (from the anode to the cathode). The small LED chips are secured inside a plastic housing, and they emit light at a givenfrequency (RED, YELLOW, etc.) when a small electric current (typically 10mA to 25mA) flows through them.

### What Is Electric Circuit

By Bertille Solange. Circuit. Published at Monday, December 18th 2017, 09:37:08 AM. Impedance essentially can be viewed as frequency-dependent resistance. While resistance of a circuit is the instantaneous ratio between voltage and current, impedance of a circuit is the ratio between voltage and current for steady-state sinusoidal signals, which can vary with of frequency. As the later parts of this section will show, the voltage and current caused by applying a steady-state sinusoidal signal to any combination of resistors, capacitors, and inductors, are related by a constant factor and a phase shift. Therefore, impedance can be expressed by a complex constant using an extended version Ohm’s law.

##### Electric Circuits Examples

By Jessica Mireille. Circuit. Published at Monday, December 18th 2017, 09:02:51 AM. Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across those two points. It means that more the resistance lesser current would flow. I=V/R This would apply to any component of a circuit. For example conductors would increase the current flow and the inductors would decrease it.

###### Relationship Between Resistance And Voltage

By Charlotte Myriam. Diagram. Published at Monday, December 18th 2017, 08:48:15 AM. There are two commonly used capacitor symbols. One symbol represents a polarized (usually electrolytic or tantalum) capacitor, and the other is for non-polarized caps. In each case there are two terminals, running perpendicularly into plates. The symbol with one curved plate indicates that the capacitor is polarized. The curved plate represents the cathode of the capacitor, which should be at a lower voltage than the positive, anode pin. A plus sign might also be added to the positive pin of the polarized capacitor symbol.
