What do you mean by polarity in DC welding? The term 'polarity' is used to describe the electrical connection of the electrode in relation to the terminal of a power source. Withdirect current(DC), when the electrode is connected to the positive terminal, the polarity is designated as direc...
Your doctor will attach electrodes to your skin to record the electrical activity of your heart. Cardiac computerized tomography (CT) scan. This machine collects images of your chest and heart while you lie on a table. Magnetic resonance imaging (MRI). This machine produces a magnetic field to...
Now, applying KVL (Kirchhoff’s Voltage Law) in loop a-b-c-d to the equivalent circuit of RLC notch filter, we get, Now, at the series resonance condition, the resonant frequency is given by And the Q-factor is given by, Where, = Bandwidth = while, is the lowest cut-off frequenc...
What is electrical susceptibility? What is the electric flux? What is electric flux? What do you mean by fibre optics? What is electromagnetism? Explain it with an example. What is permeability? What is an equilibrium? What is the principle of quantization? What is hysteresis? What is resonance?
Some lithium battery designs use not a solution of lithium ions as an electrolyte but a solid lithium alloy, frequently aceramic. Similar to graphene, the idea is that electrons can flow freely through the crystal matrix of ceramics, as they do through graphene's wandering resonance bonds. Thes...
Oligodendrocytes produce and maintain the myelin sheath that coats and insulates the axon, making electrical conduction more efficient. Ependymal cells produce CSF (cerebrospinal fluid), which is located within the ventricles of the brain and in the subarachnoid space that surrounds the brain and spina...
What is the electrical field in the middle of the square? What is a lvdt transducer? At what direction will a compass spin when at the North Pole? What are the units of electric field? What is geomagnetic activity? What is a wormhole?
shaft resonance, as illustrated in the graphs above. Critical failures can happen If the oil whip occurs at much higher speeds because resonances keep getting excited. To prevent failures caused by vibrations related to oil whirl and oil whip, the vibration tolerance limit is usually set ...
What do you mean by an electroscope? Define charge density. What is Coulomb's law? Explain briefly. Explain the difference between formal charge and resonance. What is the meaning of equipotential? What is meant by the interference of light? Define electrostatic. What is the principle of quanti...
a memory card uses flash memory technology to store data. flash memory is a type of non-volatile storage that retains data even when the power is turned off. when you save data on a memory card, it is written into the flash memory cells using electrical charges. these charges can be ...
