Electric circuits use electric power to perform some function, like energize a heating or lighting element, turn a motor, or create an electromagnetic filed. Electronic circuits differ from electric circuits in that they use devices that can themselves be controlled by other electric signals. Restated, electronic circuits are built from devices that use electricity to control electricity. Most electronic circuits use signals that are within 5 to 10 volts of ground; most circuits built within the past several years use signals that are within 3 to 5 volts from ground. Some electronic circuits represent information encoded as continuous voltage levels that can wander between the high and low voltage supply rails – these are called analog circuits. As an example, a sound pressure level transducer (i.e. a microphone) might drive a signal between 0V and 3.3V in direct proportion to the detected sound pressure level. In this case, the voltage signal output from the microphone is said to be an analog ifthe sound pressure wave itself. Other circuits use only two distinct voltage levels to represent information. Most often, these two voltage levels use the same voltages supplied by the power rails. In these circuits, called digital circuits, all information must be represented as binary numbers, with a signal at 0V (or ground) representing one kind of information, and a signal at 3.3V (or whatever the upper voltage supply rail provides) representing the other kind of information. In this series of modules, we will confine our discussions to digital circuits.

By Alix Loane. Circuit. Published at Wednesday, December 27th 2017, 08:20:06 AM. Voltage is measured in units of Joules per Coulomb, known as a Volt (V). It is important to remember that voltage is not an absolute quantity, rather, it is always considered as a relative value between two points. In an electronic circuit, the electromagnetic problem of voltages at arbitrary points in space is typically simplified to voltages between nodes of circuit components such as resistors, capacitors, and transistors

By Sasha Sara. Circuit. Published at Wednesday, December 27th 2017, 06:37:54 AM. An inductor is a device that stores energy in the form of current. The most common form of inductors is a wire wound into a coil. The magnetic field generated by the wire creates a counter-acting electric field which impedes changes to the current.

These diagrams use symbols to illustrate what electronic components are used and where they’re placed in the circuit. These symbols are graphic representations of the actual electronic components.

Current is measured in the unit of Coulombs per second, which is known as an ampere (A). In an electronic circuit, the electromagnetic problem of currents is typically simplified as a current flowing through particular circuit components.

Where should the connections be made and how to connect them. I have found that the best place for a central ground to be at the signal input ground. This will be where the connections to other external equipment is made. In a typical audio component there will be left and right channel inputs. Each channel will be via a shielded cable from the source (CD, FM, etc.). At the input jacks I have found that you can connect the two input signal ground returns together (not to the chassis) using isolated jacks provided you do not run shielded cable with both ends connected together internally to the unit. This part is often hard to envision, but you do not want multiple ground paths for the signal. This is likely to cause a ground loop, more about that later. A common error is to connect the signal grounds together at the input jacks and then run shielded cable inside the unit to something like a volume control and connect the shields together there. The shields then acts as conductors and not solely as shields. Use only one end of the shield inside equipment. If needed, run a separate ground wire to the volume control or where ever the signal is going. It will be the ground reference for the signal and the shields will be only shields. This can greatly improve the signal to noise in a piece of equipment.
