  1. How are current and voltage related to torque and speed of a …

    Sep 3, 2012 · A DC motor can be approximated as a circuit with a resistor, and voltage back-emf source. The resistor models the intrinsic resistance of the motor windings. The back-emf …

  2. 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 …

  3. 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}\$ …

  4. 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 …

  5. How much voltage/current is "dangerous"? - Electrical Engineering …

    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 …

  6. voltage - "Ground" vs. "Earth" vs. common vs. negative terminal ...

    Aug 4, 2014 · 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 …

  7. voltage - What is the difference between Vrms and Vm? - Electrical ...

    Apr 8, 2013 · 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 …

  8. voltage - Whats does "hr" mean among "V" and "Ah" in batteries ...

    Dec 2, 2015 · 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.

  9. voltage - Is power proportional to V or V^2? - Electrical …

    Jan 20, 2021 · If the resistance is constant, then increasing the voltage increases the current proportionally, exactly proportionally in the ideal case. Power is not proportional to voltage …

  10. voltage - Minimum clearance between two traces that have a …

    Aug 30, 2017 · The accepted creepage distance depends on the Comparative Tracking Index (CTI) of the pcb material (in the table it is the "material"), on pollution degree, if traces are on …
