What is inductive reactance-?
There is no such term as 'inductance reactance'; the correct term is 'inductive reactance'. This is the opposition to the flow of a.c. current, due to the inductance of the load, and the frequency of the supply, and is measured in ohms.Inductive reactance is directly proportional to both the supply frequency and the load's inductance.
What is the relation of load resistance with bandwidth?
The load resistance in a circuit can significantly affect its bandwidth, particularly in amplifiers and filter designs. A higher load resistance typically leads to a narrower bandwidth due to increased output impedance, which can limit the frequency response. Conversely, a lower load resistance can enhance bandwidth by allowing a wider range of frequencies to pass through more effectively. Therefore, optimizing load resistance is crucial for achieving the desired bandwidth in electronic circuits.
How do you calculate stress due to dynamic load?
stress is the ratio between the load and area
When a load is connected to the output voltage divider the output voltage will what?
When a load is connected to the output of a voltage divider, the output voltage will typically decrease due to the loading effect. This occurs because the load draws current, which can change the voltage across the resistors in the divider. The extent of the voltage drop depends on the resistance of the load relative to the resistors in the voltage divider. If the load resistance is significantly lower than the divider resistances, the output voltage will drop more noticeably.
What is the frequency of kissing noise of transformer?
The "kissing noise" of a transformer, often referred to as the "buzz" or "hum," typically occurs at the frequency of the alternating current (AC) supply, which is usually 50 Hz or 60 Hz, depending on the region. This noise is generated due to the magnetostriction effect in the core material, causing it to expand and contract as the magnetic field fluctuates. In some cases, higher-frequency harmonics can also contribute to the noise, but the fundamental frequency remains at the power line frequency.
Why does load shading occur?
Due to cruption among the government the loadshedding occurs
How does load shedding affect people in everyday life?
There are many problems face in our life due to load shading's disturb our study.
Why is load shedding happening?
load shed happens due to generator over load. it happens duering 1 or more engine trips as a result load shedding activated for the reason that the remaining generator/engines will suffer under frequency and over voltage.
What physical phenomenon underlies the production of beats?
It occurs due to interference or superposition between two waves of very similar frequency
In which amplifier occurs Maximum distortion?
CLASS -C amplifier is having high ditortion due to which they are not used in audio frequency work
What is traveler's diarrhea?
Traveler's diarrhea is an illness due to infection from a bacteria or parasite that occurs in persons traveling to areas where there is a high frequency of the illness.
What physics principle is used when pumping your legs in rhythm with the natural frequency of a swing?
Resonance - when pumping a swing in rhythm with its natural frequency, it produces larger amplitudes.(def. - occurs when the frequency of a vibration forced on an object matches the object's natural frequency and a dramatic increase in amplitude occurs)

There is no such term as 'inductance reactance'; the correct term is 'inductive reactance'. This is the opposition to the flow of a.c. current, due to the inductance of the load, and the frequency of the supply, and is measured in ohms.Inductive reactance is directly proportional to both the supply frequency and the load's inductance.
What is a Frequency Scintillation?
Frequency scintillation is a phenomenon in radio wave propagation where the frequency of a signal fluctuates rapidly due to variations in the ionosphere or other environmental conditions. These fluctuations can cause distortions in the signal, affecting communication and navigation systems. Frequency scintillation is often observed in satellite communications and radio astronomy.
When does maximum frequency deviation occur?
Maximum frequency deviation occurs in frequency modulation (FM) when the modulating signal reaches its peak amplitude. This deviation represents the greatest difference between the carrier frequency and the modulated frequency. In practice, it corresponds to the point where the instantaneous frequency of the carrier signal varies the most due to the modulation, often occurring at the maximum input signal level.
How are power dissipated in a load or in a resistor?
Due to energy usage and/or the reduction in conductance (increase in resistance) in a given load or resistor, some electrical energy is lost through that component. As such, a proportional drop in current and voltage occurs.
What is the change in pitch or wave frequency due to a moving wave source?
When a wave source is moving towards an observer, the pitch or frequency of the wave increases, known as a Doppler shift. This occurs because the waves are reaching the observer at a faster rate due to the source moving closer. Conversely, when the wave source is moving away from the observer, the pitch or frequency decreases.
