A transformer is two or more coils coupled by magnetic induction. It helps keep the frequency and reduce tension in an AC circuit. Motor A motor is a device that can transform electric energy into mechanical en
A flex sensor is a variable resistor. It works by increasing the resistance in the circuit the more the component bends.Spectra Symbol has been at the forefront of flex sensor technology since before 1989and the development of Nintendo’s disruptive Power Glove. ...
The RC time constant is a measure of how fast the circuit can respond to changes in conditions, such as attaching the battery across the uncharged capacitors or attaching a resistor across the charged capacitor. The voltage across a capacitor cannot change immediately; it takes time for the ...
Symbol of a resistor is……… View Solution View Solution A capacitor is connected to a variable source of potential. Current flowing in the circuit and potential across the plates of capacitor at time t are shown in figure. Capacity of the capacitor is View...
The V-I characteristic curve of Varistor is similar to that of a Zener diode. It is bi-directional in nature, since we see that it operates in both first and third quadrant. This feature makes it suitable to connect it in a circuit with either AC or DC source. For an AC source it ...
3. Electric pressure that causes a current to flow in a circuit; it is the energy put into the circuit by the source per unit electric charge that it supplies to the circuit. The unit of emf is the volt, being the electromotive force required to cause a current of 1 ampere to flow ...
The Above circuit shows theRC phase shift networkand DIAC controlled TRIAC for the light dimming application. The voltage applied to the gate terminal of the TRIAC is varied by the RC arrangement involving the Resistor R3 and the capacitor C3. When the device is in its OFF state the rate ...
The vector stencils library "Semiconductor diodes" contains 24 symbols of semiconductor diodes for drawing electronic schematics and circuit diagrams. "In electronics, a diode is a two-terminal electronic component with asymmetric conductance; it has low (ideally zero) resistance to current in one ...
A circuit for digitizing an analog signal generated from a photoelectric conversion of reflected light when scanning indicia having spatially-separated, light-reflective portions bounded by edges incl
7. A hand-held bar code scanning device according to claim 1 wherein said light source is a solid state diode. 8. A method of reading bar code symbols, comprising the steps of: (a) activating a light source in a hand-held unit by a control circuit in said hand-held unit to generat...
