By putting many of these out and back combinations together, you can get a useful voltage. A single out and back is called a thermocouple, and can be used to sense temperature. Many together is a thermocouple generator. Yes, those actually ...Thu, 02 Apr 2026 06:07:00 GMThttps://electronics.stackexchange.com/questions/517753/what-exactly-is-voltageAnd also if voltage is like gravitational potential energy, how does more voltage mean more current? And here our nice analogy breaks down. In this sense voltage is more like pressure in a water pipe.Sat, 28 Mar 2026 06:20:00 GMThttps://electronics.stackexchange.com/questions/10962/what-is-forward-and-reverse-voltage-when-working-with-diodesThe 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".Thu, 26 Mar 2026 10:26:00 GMThttps://electronics.stackexchange.com/questions/39387/how-are-current-and-voltage-related-to-torque-and-speed-of-a-brushless-motorVoltage instead "regulates" how fast a motor can run: the maximum speed a motor can reach is the speed at which the motor generates a voltage (named "Counter-electromotive force") which is equal to the voltage it receives from battery (disregarding power losses and frictions for simplicity).Thu, 02 Apr 2026 08:59:00 GMThttps://electronics.stackexchange.com/questions/75448/how-to-reduce-dc-voltage-using-resistorsHow would one go about using a 12 V DC power source to power something which needs 4.5 V DC using resistors? Is there a way to determine how much adding a resistor would drop the voltage?Thu, 02 Apr 2026 12:05:00 GMThttps://electronics.stackexchange.com/questions/755438/voltage-across-vce-in-a-common-emitter-bjtIn this case, the voltage across the current source I depends only on R. With other words: The voltage across a constant current source depends on the external network only. Therefore, the voltage Vce depends on IcRc and Vcc only. When there is an emitter resistor Re we have; Vce=Vcc-IcRc-IeRe.Tue, 24 Mar 2026 07:58:00 GMThttps://electronics.stackexchange.com/questions/19103/how-much-voltage-current-is-dangerousLikewise, 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.Thu, 26 Mar 2026 08:17:00 GMThttps://electronics.stackexchange.com/questions/256336/does-led-brightness-change-with-voltageThe voltage only needs to be slightly above the forward voltage rating of the LED. A common way to control brightness is through pulse width modulation (PWM). Instead of giving a LED less voltage, to dim it, you give it the full voltage, but in repeating bursts. The duty cycle determines brightness.Thu, 02 Apr 2026 17:27:00 GMThttps://electronics.stackexchange.com/questions/740867/why-doesnt-the-mosfet-short-when-i-apply-a-voltage-greater-than-the-max-ratingThe maximum gate to source is 20V. However, the FET is not damaged when I increase the gate voltage to greater than 20V. I thought that going above the gate to source this would cause the drain to source to short. Firstly why does the FET not get damaged when the V gs is greater than the maximum of 20V?Mon, 16 Mar 2026 21:36:00 GMThttps://electronics.stackexchange.com/questions/92678/three-phase-power-supply-what-is-line-to-line-voltage2 Line to line voltage for a 3phase network (120deg separation) is sqrt (3)*phase voltage. So for a 230V 3ph network the line-line is 400VThu, 02 Apr 2026 00:02:00 GMT
