Circuit Components: the Resistor The resistor is the simplest, most basic electronic component. In an electronic circuit, the resistor opposes the flow of electrical current through itself. It accomplishes this by absorbing some of the elec...
critical property, which affects on, the Ohmic heating, is the electrical conductivity of the food. Variation of the salinity, pH and applied electrical power during the Ohmic heating may alter the electrical conductivity Several models hav...
Ohm's Law. While doing experiments on how well metals conducted electricity, German physicist Georg Ohm discovered the law in 1827. Ohm's Law is the equation V = I R and is used in both AC and DC circuits. Knowing two items in this equatio...
is a specialized rectifier circuit producing an output which is theoretically an integer times the AC peak input, for example, 2, 3, or 4 times the AC peak input. Thus, it is possible to get 200 VDC from a 100 Vpeak AC source using a doubl...
power transmission. Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits due to this instability occurs in the power system. With the scheme proposed in this paper, it is possible to load these lines very close to...
speed limitation, maintenance and reliability. One feature of the latter is that the slip power becomes easily available from the slip rings, which can be either mechanically or electronically controlled for motor speed adjustment. However,...
from a source to a load, through a given surface as in Fig. 1. In the network of Fig. 1, the voltage waveform v(t) (not necessarily sinusoidal) is given by the source, and the current waveform is determined by the response of the load. In t...
