- What exactly is voltage? - Electrical Engineering Stack Exchange
What is voltage? It's a stack of invisible membranes which fill the space between charged capacitor plates Voltage is the pattern of concentric onion-layers which surround any charged object, with the onion-layers running perpendicular to the flux-lines of the electric field So, 'stacks of voltage-layers' is one way of describing an electric
- voltage - Ground vs. Earth vs. common vs. negative terminal . . .
Voltage and Current In electricity there are positive charges (usually protons) and negative charges (usually electrons When one object is positively charged, and another is negatively charged, then there exists an electrostatic field This is the voltage, or the potential for charge to be able to be moved by the electrostatic field
- voltage - What is VDD in this context? - Electrical Engineering Stack . . .
For power supply flexibility, the MPU-60X0 operates from VDD power supply voltage range of 2 375V-3 46V Additionally, the MPU-6050 provides a VLOGIC reference pin (in addition to its analog supply pin: VDD), which sets the logic levels of its I2C interface The VLOGIC voltage may be 1 8V±5% or VDD
- voltage - How does data travel inside a wire? - Electrical Engineering . . .
Current and voltage are inseperable The current is flowing because there is a voltage on the wire, and there is a conductive path from that voltage to a lower voltage So we can say the data is encoded as voltage pulses or current pulses, it doesn't really matter Often a high voltage (5 V) indicates a "1" and a low voltage (0 V) indicates a "0"
- voltage - What is the difference between Vrms and Vm? - Electrical . . .
The RMS value of a waveform is the DC-equivalent voltage It means, that if you have a sine wave with an RMS value of 10 volts RMS, in order to deliver the same power via DC voltage, you would need 10 volts DC Don't confuse the average magnitude with the RMS voltage; V av does not equal V rms In fact, technically, the average voltage of an
- voltage - Explain in laymans terms Vgs and Vgs(th) of MOSFETs . . .
Vgs(th) is the voltage at which the mosfet channel begins to conduct At this voltage, a positive voltage, it creates an electric field, which attract electrons (since our applied voltage is positive, so positive charges on gate) These accumulated electrons near the gate, form a bridge between the source and the drain (which are both n type)
- Volts vs voltage - Electrical Engineering Stack Exchange
Voltage is a difference of electric potential To simplify, it is an measure of the difference in concentration of electrons between two points Volts is a unit of measure of voltage It would be pretty difficult to have exactly no electron on an electrode, and as the voltage is the difference of potential, it is always relative to somthing
- datasheet - Noise and what does V √Hz actually mean? - Electrical . . .
To convert the spectral density \$\tilde v\$ (in nV √Hz) to a voltage (in V RMS), you need to multiply it by the square root of the bandwidth: $$ v_\mathrm{RMS}=\tilde v \cdot \sqrt{\Delta f} $$ For example, if the op-amp is a TLC071, with equivalent input noise voltage density of 7 nV √Hz, and audio bandwidth, the total equivalent input
