What does it mean to say that an operation is commutative?
It means the operation has two sub-operations and it does not matter in which order they are done. An example is the addition of two numbers (but not the subtraction).
For example, 2+1=3, but also 1+2=3 so adding 1 and 2 is commutative.
What reading will be displayed on a DVOM if the scale is exceeded?
It depends on the device and manufacturer, but most digital multimeters will display "OL", which indicates an OverLoaded input for the specified range. The term "overload" doesn't necessarily mean that a voltage or current is necessarily at a dangerous level or a level that might damage the device, but rather that the upper limit of its measuring capability has been reached.
In order to protect the equipment from damage, it's a good idea to set the meter to its highest range first when working with unknown voltages or currents and make a quick measurement at that level to make sure you don't get an overload (OL) on the display. This tells you whether or not you are potentially working beyond the manufacturer specified limits of the equipment (though the manufacturer limits are usually higher than the measurement limits).
Can bias in the media be avoided Can it effect be controlled How?
Bias is avoidable, it just requires a good deal of research to find information that isn’t sponsored in some way by a news source. This means seeking out original content or reading boring political documents. An alternative is to look up media ratings on Politic Nation . com. It provides stats for major media outlets and shows which direction they lean on a partisan scale.
The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
Applications of Carey foster's bridge?
The Carey Foster bridge works on the principle of the wheatstone bridge (potentiometer)which can be used to measure fractional resistance.
4 what is the name of the circuit that adds a positive or negative dc voltage to an input sine wave?
This DC voltage is called the DC offset. Any decent signal generator will be able to add DC offset to the signal it generates. If you don't have one, simply connect a DC voltage to your signal.
What accomplishments have given you the most satisfaction in your life?
I look for a job that can help me grow with knowledge and challenge me to do my best. I also look for a job that has the ability for me to grow with the company and have potential room for advancement
What is concentric cable transmission line?
It is a shielded high voltage cable made up of center conductor with the next layer being a semi-con layer followed by a insulation layer with another layer of semi-con wrapped with a copper stranded ground and covered by a protective jacket. It is usually three wires, each carrying a phase of the three phase primary that most power companies generate today.
What are the characteristics of transmission line?
In general the conductor materials used for transmission and distribution of electrical power must have the following characteristics
1. High electric conductivity
2. Low specific gravity in order to give low weight per unit volume
3. High tensile strength in order to withstand the mechanical stress
4. Cheap and easily available
5. Should not be brittle
What is the difference between voltage and emf?
E.M.F: Is the potential difference between two terminals when there is no current i.e. circuit is open, therefore [EMF = OCV].
OCV :open circuit voltage.
Voltage: Is the potential difference between two terminals when there is current i.e. closed loop
AnswerAn e.m.f. (electromotive force) is a voltage or, more accurately, a potential difference ('voltage' is simply another word for 'potential difference'). However, it is the potential difference that appears across the terminals of a supply when it is not connected to its load. When the supply is connected to a load, this potential difference falls because of an internal voltage drop across the supply's internal resistance. So the simple answer is that an electromotive force is a supply's open-circuit terminal voltage.
Another definition is obtained from Kirchhoff's Voltage Law, from which we can say that an electromotive force is equal to the sum of all the all the voltage drops around the circuit, including its internal voltage drops.
What is the applied voltage on a circuit in which 5A is flowing and 10 w is generated?
Is step signal is a DC signal?
A: while a step can be of both polarity but it is a level change and it is DC LEVELS
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
What is it called when voltage is lost across a portion of a circuit?
This is often called a "voltage drop".
One ohm.
Draw and explain the v-i characteristics of a p-n junction?
As you can't draw here, see link.
Digital bandwidth refers to the capacity of a communication channel to transmit data over a given period. It is typically measured in bits per second (bps) and indicates how much information can be sent or received at once. Higher bandwidth allows for faster data transfer rates, enabling activities such as streaming videos, online gaming, and large file downloads with greater efficiency. Essentially, it determines the speed and quality of internet connections and other digital communications.
When checking the high pressure cutout switch with an ohm meter there should be continuity between?
terminals one and two
What is the meaning of true differential TDR?
can you give me the information about True differential TDR? Ples.
Your IF stages, normally three is a filter to give you better selectivity, it filters out all second channels and only let the preferred channel thru to your detector stage, the three stages is always tuned slightly off beat, in SW: 477KHz, 476KHz, 477KHz
