Systems such as those encountered in mechanics, thermodynamics, and hydraulics can be represented by analogous electric networks, from the response of which the system characteristics can be investigated. The analogy, of course, is a mathematical one: that is, two systems are analogous to each other if they are described by similar equations. The analogous electric quantities for a mechanical system are listed in Table.
Consider a tank filled with water, as shown in Figure, with input flow rate Fi and output flow rate Fo = h/R, where h is the fluid level or head and R is related to the diameter of the pipe, denoting the fluid resistance. Let A be the cross-sectional area of the tank. We may think of the fluid as being analogous to charge, and the fluid flow as being analogous to current. Then, in effect, the water tank acts as a capacitor storing charge, which is fluid in this case. This analogy is illustrated in Table.
Enhancement type MOSFET In these types of devices operate by comprising a channel enhanced in the semiconductor material in which no channel was constructed, they are termed
How to design an Oscillator Circuit (500 MHz range) with no Op amps?
Thermal noise This is the most significant noise in an ampli?er. It is produced by random movements of electrons in the resistors. This is caused by the ?uctuations in the volt
Q. Consider a 240-V supply feeding a resistive load of 10 kW through wires having a total resistance of R = 0.02 . For the same load, let a 120-V supply be used with a total wire
Q. Give the classification of Oscillators? Depending on the type of the output waveform, oscillators are classified as sinusoidal (or harmonic) oscillators and relaxation osci
Magnetic flux and flux density Magnetic flux is the amount of the magnetic field (or the number of lines of force) formed by a magnetic source. The symbol represented magnetic
