An ideal switch will present supply voltage V b across the primary, so in the ideal case V p = V b. V s, voltage across the secondary winding; V z, fixed load voltage caused by e.g. by the reverse voltage of a Zener diode or the forward voltage of a light-emitting diode (LED). I m, magnetizing current in the primary
A number of light sculptures feature in this elaborate display which surrounds a Nativity scene set in a basement garage. Lights are sometimes mounted on frames—typically metal for large lights and plastic for miniature ones. These were first used for public displays on lampposts, street lights, and telephone poles in cities and towns. For ...
Optical isolator for laser experiments. An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction.It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity.
Solid state relay with green LED Solid state contactor PCB mount solid-state DIL relay. A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals.
Diagram of a simple circuit with an inductance L and a flyback diode D.The resistor R represents the resistance of the inductor's windings. A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.

The PIN diode obeys the standard diode equation for low-frequency signals. At higher frequencies, the diode looks like an almost perfect (very linear, even for large signals) resistor. The P-I-N diode has a relatively large stored charge adrift in a thick intrinsic region. At a low-enough frequency, the stored charge can be fully swept and the ...
The DTOC relay has been used extensively in the United Kingdom but its inherent issue of operating slower for faults closer to the source led to the development of the IDMT relay. [1]: pp 30-31 A definite time over-current (DTOC) relay is a relay that operates after a definite period of time once the current exceeds the pickup value. Hence ...
