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 …

Yes, it is correct for instantaneous difference for a 230V RMS system. 230V RMS is $$ \sqrt2 \cdot 230V$$ line-to-line, and

Mar 3, 2011 · 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 …

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 …

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} …

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 …

Running a part at a lower voltage or current means less heat is generated. Powering a 16v max capacitor, at 16v, is stressing it. Running a 20mA led at 20mA will only provide x number of …

May 1, 2014 · To keep it very simple, if you have a 1000 watt heater intended to operate on 120 V 60 Hz power, it will produce the same heat at 50 Hz or 400 Hz, provided the voltage remains …

Also RMS of voltage times RMS of current is the apparent power like someone mentioned before, but god alone knows what that means. Also Prms = Pave when load is resistive. So a more …

Oct 2, 2024 · Above, v is the output voltage you want. f is the sinusoidal frequency. And r is an integer to use for oversampling of f. I set it to 25, but feel free to set it to 100, or something …
