Certain types of radio antennas (or their feedlines) require a connection to ground. Since the radio frequencies of the current in radio antennas are far higher than the 50/60 Hz frequency of the power line, radio grounding systems use different principles from AC power grounding. The "third wire" safety grounds in AC utility building wiring were not designed for and cannot be used for this purpose. The long utility ground wires have high impedance at certain frequencies. In the case o… WebOct 24, 2012 · The NEUTRAL wire is used to conduct the return current.

WebMar 3, 2024 · Ideal Ground. In electrical circuits, current flows only if there is a closed path. A return path must exist for the current to flow back to the source. The return path is provided by a common point, called ground, in circuits. Ideally, there is no resistance or parasitic capacitance in ground connections. The circuit components are connected ...

WebSep 24, 2024 · Resistance also affects how electricity travels through wires. A cable that has a low resistance has a high flow of electrons, while the one with high resistance has a low flow of electrons. The measurement of resistance is Ohms, and too much resistance in a circuit can cause an overload which might potentially result in a fire. traditional book publishers in indiaWebcurrent to flow: 1) there must a voltage poten-tial, and 2) there must be a path to ground. Current takes the path with the least resistance, and in most cases, this is through the motor bearings.
