Coupling and Bypassing Capacitors: Coupling Capacitors - To use a transistor circuit to amplify or otherwise process an ac signal, the signal source must be connected to the circuit input.…
Voltage Source Inverter Control of Induction Motor: Variable frequency and variable voltage supply for induction motor control can be obtained either from a voltage sourve inverter (VSI) or a cycloconverter.…
Electric Stress Control: The Electric Stress Control distribution is usually governed by the Poisson's equation: where φ is the potential at a given point, ρ is the space charge density…
pH Measurement Methods: pH is defined as the negative logarithm of the active hydrogen ion. It is a measure of the acidity or alkalinity of an aqueous solution. The pH…
Digital Capacitance Meter Block Diagram: Digital Capacitance Meter - Since the capacitance is linearly proportional to the time constant, when a capacitor is charged by a constant current source and…
Split Phase Motor: When a motor is provided with two windings, even though these are excited from the same voltage (supply being single-phase), the currents in the two windings can…
