What does E stand for in electronic circuits like R for resistance?
Wiki User
∙ 12y ago
Electromotive force or electromotance measured in volts.
Just think of it as volts. Like in Ohm's Law:
R=E/I or I=E/R or E=I*R
E stands for volts, I stands for current (from the French word intensite'),
and R stands for resistance.

Reason for using wire wound resistor in electronic circuit?
There is many uses for the resistor in electronic circuits, like current limiting, voltage division, R/C oscillators and many more. Without the resistor electronics is not possible
What is self resistance?
Self resistance is exactly what it sounds like it would be. It is the resistance that you make happen on your own.
What are examples of man made electricity?
like battery or circuits
Why is input resistance low and output resistance high in transistor?
The input resistance of a trasister is jst like pn junction of a diode which has a breakdown voltage of .7v for silicon and the output resistance is like a reverse bias of a diode and hence the resistance is high
Is the function of a capacitor in an electric circuit to increase circuit power?
No, a capacitor in a circuit will not increase power. The capacitor is an electrical component that is used to provide resistance to a change in voltage. That's what capacitance is; it's how we define it. A capacitor (cap) can also be used to "couple" or "transfer" an AC signal in a way that isolates any DC component. Capacitors are used in waveshaping circuits in electronic circuits. The are used to store charge to "smooth" the output of a power supply. In power distribution systems, they are employed for "offsetting" the phase shifts introduced by the large number of inductive loads (like motors) on these circuits. And this things are just a start. Capacitors do not increase power in a circuit. They "give back" to a circuit, but only after "taking from" the circuit at another time. They are what is called a reactivecomponent, but they are passive. They don't "make" power and put it in a circuit.

Why in DC it is called as Resistance and impedance in AC Circuits?
Resistance applies to both d.c. and a.c. circuits, and is determined by the resistivity, length, and cross-sectional area of a conductor.In d.c. circuits, resistance is the only opposition to the passage of current. However, in a.c. circuits, the flow of current is opposed, not only by resistance, but also by reactance. Reactance is caused by a circuit's inductance or capacitance, or both, and varies with the frequency of the supply. Like resistance, reactance is also measured in ohms.So, in a.c. circuits, the combination of resistance and reactance is called 'impedance'.Impedance is not the algebraic sum of resistance and reactance, but the vectorial sum. So if, for example, an a.c. circuit had a resistance of 3 ohms and a reactance of 4 ohms, the impedance would be 5 ohms, not 7 ohms.
How can you solve resistance to complicated circuits like diamond shaped circuits?
One way is to use Thevenin's theory and methods. Léon Charles Thévenin was a French telegraph engineer who extended Ohm's Law to the analysis of complex electrical circuits.
What are eda tools?
These are Electronic Design Automation tools. These tools are used to design and implement electronic circuits virtually using a computer. Programming languages like VHDL, Verilog can be used for this purpose.
Are parallel circuits like series circuits?
They are not exactly the same. A series circuit is one complete circuit with not other pathways. A parallel circuit is a complete circuit with multiple pathways . The resistance of a parallel circuit is completely different from the resistance of a series circuit. Therefore, this affects the voltage and the current produced,
What are the safety hazards of electronic circuits?
there are several ways of safety hazards in electronic circuits those are those are - 1- capacitors are dangerous if they charged discharge it before handling. 2- the high voltages are present somewhere in electronic circuits like EHT on television mind these. 3> static charge of body can damage cmos ics don't touch them from naked hand. 4> ground all equipments before using them it will prevent from electric shock.
How to draw electronic circuits consisting of simple components like resistor and capacitor?
You can try Express PCB http://www.expresspcb.com/ExpressPCBHtm/Download.htm
Describe the effect of having or loose contracts in electric circuits?
Loose contacts can act like on/off switches in the circuit as they make/break connection. In sensitive circuits, the added resistance during contact may also affect the performance of the circuit itself, particularly if Resistance is part of the circuit design.
What are the ohms in an open device?
The resistance [ohms] of an open electronic device is, by definition, infinite, just like a perfect insulator.
What is meant by circuit?
circuits are a combination of resistors, parallel and series connections between components to accomplish a task. Every electronic device has circuits.Circuits can be simple, like turning on and off a light to very complex like a computer mother board with literally 100,000 circuits to accomplish many tasks.
What are the limitations of ohms law?
It requires the ability to multiply and divide. It requires the ability to mentally separate voltage from current and to understand resistance and when to add resistance for series circuits and worse identify and calculate parallel loads.
How do you troubleshooting the electronic circuits?
A: begin by a visual inspection like carbon deposits and other obvious damages. second step is verify power available to the circuit. third step is a mandatory instrumentation like an oscilloscope .
