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\$ –
What is the difference between reverse stand off voltage and . . . V RWM is the Reverse Working Voltage, the voltage a curcuit works with (e g 3 3 V or 5 V for microcontrollers) At this voltage, the TVS diode should have no effect on the circuit V BR is the Breakdown Voltage at which it starts conducting higher currents This voltage should be higher than the maximum voltage which the power supply would
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
How to calculate voltage drop over and power loss in wires Now, we want to know what the voltage drop over one piece of wire is using \$\text{V}=\text{I}\cdot{}\text{R}\$: \$\text{V}=0 01961\cdot2 5=0 049025V=49 025\text{mV}\$ We can also calculate the voltage over \$\text{R}_{\text{load}}\$ in the same way: \$\text{V}=0 01961\cdot250=4 9025\text{V}\$ Anticipating on voltage loss
What is forward and reverse voltage when working with diodes? The reverse voltage is the voltage drop across the diode if the voltage at the cathode is more positive than the voltage at the anode (if you connect + to the cathode) This is usually much higher than the forward voltage As with forward voltage, a current will flow if the connected voltage exceeds this value This is called a "breakdown"
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)
