To calculate the voltage across an inductor, the formula is: All you have to know to calculate the voltage across the inductor isL, the Inductance of the Inductor which is expressed in units, Henry, and the derivative of the current going through the inductor. Example If the current going t...
You can calculate the amount of wire of width W needed to make a coil of radius R and length L by using the formula 2?R x (L/W). This formula is equivalent to the circumference each loop of the wire makes times the number of such loops in the coil. This formula is, however, a...
the inductor voltage is clamped to VINbecause the VFET node voltage is forced to ground by a current path through the FET’s body diode. Current flows through D2 until the voltages across C1 and C2 equalize, but current through the FET’s body diode continues until...
ignition coils consist of two sets of copper wires that are wrapped around an iron core. The electric energy from the core is transferred to the distributor
When the PMOS is on, voltage across the inductor VL = Vi -Vo Peak Inductor current IL=VL Ton / L1 The inductor current generates a magnetic flux inside the ferrite toroid. The magnetic flux energy EL=1/2 * L1 * IL^2 When the PMOS is switched off, the inductor current flows will no...
A snubber is an electrical device that prevents voltage spikes due to sudden changes in current. These voltage spikes, or transients, can damage the circuit and cause arcing and sparks. One type of electrical snubber is the RC snubber, which is composed
The maximum energy that an x-ray can have is limited to the energy of electron producing it, itself directly proportional to the voltage applied on the tube’s anode. Often this energy is measured as kilovolts peak, or kVp. In reality the majority of the x-rays produced are low energy,...
An equipotential is a path through space where the voltage is constant along that path – similar to electric field lines. Electric potential is in units of joules (energy) per coulomb (electric charge), so it describes the amount of energy exerted per unit of charge. We can also describe ...
Before you begin, you’ll want to get an idea of how muchoutput poweryou want from the amplifier. You’ll also need to know theimpedanceof your speakers and theinput voltageof your audio source. Be sure to check the TDA2050’s datasheet to find the absolute maximum ratings for these pa...
By the time this happens, the filaments have already ionized the gas in the fluorescent tube, creating an electrically conductive medium. The tube just needs a voltage kick across the electrodes to establish an electrical arc. This kick is provided by the lamp'sballast, a special sort of tran...
