Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What volts ohm ampere and watts are terms associated with this?
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
What is the capacitance of parallel plate capacitor?
We know the Electric Field, E, is equal to:
E=V/l, where V is voltage, l is distance.
V=E*l
Capacitance, C=q/V, and C=q/(E*l)
Hence capacitance is inversely proportional to the distance separating the plates.
How shunt helps to extend the range of ammeter?
A shunt is connected in parallel with an ammeter.
Any current applied to parallel devices will divide betwen them, so the ammeter will pass only a part of the total current.
What will happen if current is more than required in diode?
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes.
Current = voltage divided by resistance.
Why digital and analog ground must be separated?
Digital GND has more noise than Analog GND. So never mix up Digital GND to Analog GND to avoid the coupling from Digital to Analog GND
Why will one consider an operational amplifier as an ic circuit?
Operational amplifiers are usually bought as an i.c., but they may be constructed with discrete compenents too.
By the way, since i.c. means integrated circuit, your "ic circuit" reads as "integrated circuit circuit".
Why epoxy lens used in led diodes?
Epoxy lens consists of light scattering particles which increases the brightness of LED.
When performing a flip test to generate a topic what do you do?
scan through magazines and jot down answers
Ideally, the output voltage should be zero when the two inputs are equal to each other. Generally, an offset null adjustment is provided to do that - you short the two inputs together, and adjust the null for zero output. You just have to be careful, because high performance op-amps can "see" even the short sections of wire used for the jumper and treat that as an inductor, creating an RF oscillator. High frequency rolloff compensation usually is added to prevent this.
Which component can you use to replace ic um66?
UM66 is a type of circuit used in electronics. It can be replaced with BT66 if a replacement is needed.
What is the current in a lamp if 72 coulombs pass through it in 24 seconds?
72 coulombs in 24 seconds is 3 amperes.
One ampere is one coulomb per second.
What is the value resistor brown black orange?
Brown (1) - black (0) - orange (4 more 0's) - 10,000 ohms.
What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese.
Ans 2 .
the current in series circuit of constant resistance will always be the same . It will not effect the current .
Is it possible to measure capacitance using only one 555 timer?
yes, it is possible to measure capacitance using only one 555 timer for it's monostable operation. When the output is high time is given by the equation t=1.1RC. From the output pulse measuring t(high) and then by measuring R we can calculate the capacitance.
What is meaning of stop mode in TOD energy meter how can reverse energy calculated in TOD meter?
WikiAnswers does not give information about illegal acts, such as tampering with with a TOD meter.
What should be the value of Vce if the base terminal of a transistor is open?
It would be zero because there is a leakage.
What is the smallest primary voltage division on a analog multimeter?
0 is smallest primary voltage division
