The timedependent characteristics of voltage or current signals can take a number of forms including DC, sinusoidal (also known as AC), square wave, linear ramps, and pulsewidth modulated signals. Sinusoidal signals are perhaps the most important signal forms since once the circuit response to sinusoidal signals are known, the result can be generalized to predict how the circuit will respond to a much greater variety of signals using the mathematical tools of Fourier and Laplace transforms.

An electric current is defined as free flow of electrons and the motivating force behind that free flow of electrons is called Voltage. Voltage is the measurement of potential energy that would move the electrons between two points. Voltage is the push that the electrons require to move within a circuit. Voltage is measured by Volt and Current is measured by Ampere.

The ground is a circuit node to which all voltages in a circuit are referenced. In a constant voltage supply circuit, one terminal from each voltage supply is typically connected to ground, or is grounded. For example, the negative terminal of a positive power supply is usually connected to ground so that any current drawn out of the positive terminal can be put back into the negative terminal via ground.

The result now is a two-part speed-torque curve which features constant torque from zero speed until it intersects the motor’s natural load line, called the corner speed, beyond which the motor is in the constant power region.

Completing an electrical engineering degree and then getting a job in the field means you will see a lot a lot a lot of these schematics. It’s important to understand exactly what is going on with these. While they can (and will) get very complex, these are just a few of the common graphics to get your footing on.

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.
By Jessica Mireille. Power. Published at Tuesday, June 20th 2017, 23:07:42 PM. Voltage regulation is the process of holding a voltage steady under conditions of changing applied voltage and changing load current. Many electronic systems require a stable power supply voltage and use voltage regulators to accomplish that.

While electrical is the basis of everything, electronic is a subset of electrical. An electrical circuit deals with just the flow of electrons and has components like resistors, inductors and capacitors and uses Alternating Current Source; while electronic circuit deals with the transformation of current and controlling the motion of the electrons and uses Direct Current Source. An electrical circuit is termed as Passive because it doesn’t have any such component that reacts to the current/voltage that passes through them and electronic circuit is called active because of the additional components like diode or a transformer that react to the current/voltage that passes through.
