- 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
- How much voltage current is dangerous?
Likewise, if the current and voltage are below a certain level, a person can--given enough time--safely absorb an arbitrarily large amount of electrical energy Further, if voltage is sufficiently low, the amount of current that can flow as a consequence of such voltage will be too low to cause harm \$\endgroup\$ –
- 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 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
- 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
- voltage - What is the difference between a linear regulator and an LDO . . .
Linear regulators control the output voltage by adjusting the current through an output transistor In all linear regulators, there is a minimum difference between the input voltage and the output voltage that you have to maintain Take the ancient 7805 linear regulator It needs the input voltage to be at least 2V higher than the output voltage
- voltage - Whats does hr mean among V and Ah in batteries . . .
It means that the battery has a capacity of 25 Ah when discharged in 10 hours 25 Ah is 25 Amps for 1 Hour which is equivalent to 2 5 Amps in 10 Hours
- 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
