The most common form of capacitors is made of two parallel plates separated by a dielectric material. Charges of opposite polarity can be deposited on the plates, resulting in a voltage V across the capacitor plates. Capacitance is a measure of the amount of electrical charge required to build up one unit of voltage across the plates.

Most of the electrical symbols can be changed in their appearance, styles and colors according to users requirements. Electrical symbols are used to represent various electrical and electronic devices in a schematic diagram of an electrical or electronic circuit.

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

All schematic capture programs will produce output for inclusion in publications. However, these programs have different goals, and it shows. Rarely is the output of a schematic capture program really suitable for publication; often it is not even readable, or cannot be scaled. Engineers who really want to have a useful schematic drawing of a circuit usually redraw the circuit in a general drawing program, which can be both tedious and prone to introducing new errors.

The ratio between voltage and current is known as resistance. For most metallic conductors, the relationship between voltage and current is linear.

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.

In this tutorial, we’re going to give you a brief overview of common electronic components and explain what their functions are. You will then learn about schematic diagrams and how they are used to design and build circuits. And finally, you will put this information to use by creating your first basic circuit.

It is possible for RO to be negative – an undesirable characteristic often caused by poor layout design in the regulator wiring resulting in inadvertent positive feedback. With negative output resistance the output voltage increases with the load current.
