What is the equivalent of one erlang?
The erlang is a dimensionless unit that is used in telephony as a statistical measure of offered load or carried load on telephone circuits or telephone switching equipment. The number of erlangs represents the number of phone calls in progress at a given moment, or the average number of concurrent calls carried by the circuits (or other service-providing elements), where that average is calculated over some reasonable period of time.
Do fuses protect against - A short circuits B overoading C lightning surges D large ground faults?
Short circuits.
What is a h diagram in math?
A geometric model, termed an H diagram, is an effective visual aid in the synthesis of combinational logic circuits. The model is derived by means of coordinate transformations of a hypercube, resulting in a simple two-dimensional framework for mapping a binary function. The H diagram can be expanded to accommodate an arbitrary number of variables, while maintaining a mathematically consistent pattern that permits the extension of simple geometric interpretations to problems of more complexity.
Is an Eulerian circuit traversable?
Yes. Because Eulerian circuits are a subset of Eulerian trails, all Eulerian circuits must be traversable since, by definition, a Eulerian trail is traversable.
What are reciprocal circuit elements?
Reciprocal circuit elements are those elements/circuits in which power loss/gain is same at both nodes/ends.In these types of circuits we can check the circuit or connect it in any way.
Why dont series circuits shine as bright as parallel circuits?
By connecting components in series, you are increasing the equivalent resistance (known as thevenin resistance) of the circuit. Power is equivalent to Voltage^2 / Resistance. Therefore, by increase the resistance, you are decreasing the amount of power provided by the source.
How you can calculate ampere?
Voltage (volts) divided by Resistance (ohms). For AC circuits the resistance part of this formula is replaced by "impedance" which involves the effects of capacitors and inductors as well.
What is meant by equivalent resistance of a series combination?
Answer: The equivalent resistance of a series of resistors is as follows:Suppose you have three 120 Ohm resistors:A---/\/R1\/\------/\/R2\/\------/\/R3\/\---BThe equivalent resistance of point A to point B is the resistance of R1, R2 and R3 in series.Suppose we would want to replace R1, R2 and R3 with a single resistor, R4:A---/\/R4\/\---BThe resistance of R4 would be 360 Ohms, since equivalent resistance of a series combination is:Req = R1 + R2 + R3Answer: What is meant by equivalent resistance is that if you replace (for example) two or three circuits with whatever you calculate (see the other reply, above) as the "equivalent resistance", the effect on the circuit in general will be the same. For example, the same amount of current will flow.
What is the equivalent resistance through the enire circuit of 90 volts?
Not enough information. In the case of simple circuits, usually you would add resistances that are in series, and use a slightly more complicated formula for resistance that are in parallel. You CANNOT determine an equivalent resistance known only the voltage. However, if you know the total current, you can divide the voltage by the total current to get the equivalent resistance.
Can you use resistance in place of diode in clipping circuits?
no we not use resistance in place of diode.
What are the multiple resistance circuits?
a circuit with many resistances.
What do Two circuits that are equivalent have the same of?
If the two circuits have the same input impedance they are equivalent in respect of the input impedance.
Which of the statements concerning parallel circuits is NOT true?
D. The total resistance is equal to the lowest resistance in the 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.
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.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
What is the opposition of current flow measured in?
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
