What is fiber optic communication ?
The fiber optic technology has been developed mostly for use in communication. fiber-optic communication is transmitting information from one place to another by sending pulses of light through an optical fiber. a technology that uses glass or threads to transmit data. a
What is function of a resistor in electronic circuits?
Some important functions of resistor in electronic circuits is given below. Resistor set up the proper value of voltage across it due to IRdrop. Resistors play an important role to limit the current in any electronic circuits. Resistor
Difference between shunt voltage regulator and series voltage regulator
Following are main difference between shunt voltages regulator and series voltages regulator Shunt voltages regulator Series voltages regulator Shunt voltage regulator has good voltage regulation even at high load currents. Series voltage regulator has not so good
Construction of Ceramic trimmer capacitor
The constructional diagram of a ceramic trimmer capacitor is as shown in fig. The ceramic trimmer capacities are constructed in two forms as under. Rotary type ceramic trimmer. Concentric type ceramic trimmer. The construction of rotary type
Resistor in series
Resistors are said to be connected in series, when they are daisy chained together in a single line. The current in a series circuit goes through every component in the circuit. Therefore, all of the components in a
Resistor in parallel
Resistors are said to be connected together in parallel when both of their terminals are respectively connected to each terminal of the other resistor or resistors. In a parallel circuit, each device is placed in its own
