Potential Difference and Measuring Potential Difference

potential difference explanation

Potential Difference If electrons have greater potential energy at one place than at another, then a potential difference is said to exist between the two places. Potential difference is the difference in potential energy per unit of charge, between two points.In the metric system, potential energy is measured in joules. The charge is measured in …

OHM’S LAW (Resistance and Voltage Drop)

ohm's law

OHM’S LAW There is a simple relationship between the current that flows through a conducting path and the potential difference between the ends of the path. As you increase the potential difference, the current increases, see the below circuit. The two values are proportional. That is, doubling the potential difference doubles the current. Tripling the …

What is Electric Resistance? Unit and Symbol

electric resistance

When any material flows through a pipe, it meets opposition. The opposition comes from friction between the material and the inner surface of the pipe. The friction resists the flow of the material, and it produces heat. The same is true of electricity flowing in a conductor. The moving electrons meet opposition, and the opposition …

Quantum Harmonic Oscillator

Quantum Harmonic Oscillator

Background to classical mechanics Classical mechanics is a branch of physics that studies the motion of physical bodies. Sir Isaac Newton could come up with laws to explain the behavior of matter as far as motion is concerned. Later on, the particulate nature of matter was studied as a branch of physics. A particle of …

Voltage-Controlled Oscillator Characteristics & Applications

voltage-controlled oscillator

A voltage-controlled oscillator abbreviated as VCO is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by applying a modulating signal to the control input. A VCO is also …

24 Volts and 12 Volts Transformer

24 Volts and 12 Volts Transformer

A transformer is an electrical device that achieves voltage conversion as the main function. The transformer is an essential element in electrical devices and systems as it allows power supplied to adapt to power demanded by the machine. One of the classifications of transformer types is on basis of the magnitude voltage it handles. In …

Sine Wave Generator

Sine Wave Generator

A sine wave generator is a class of functional generators that produce a sinusoid-shaped waveform or signal.  The sine wave is continuous with a smooth periodic oscillation. It is one of the most simple and basic waveforms. The waveform repeats itself after every 360°. Some modern sine wave generators use digital signal processors to synthesize …
