Why conductors are designed using smaller strands?
Two reasons:Mostly a stranded wire is far more flexible than a solid one and less likely to break after repeated flexing.At AC frequencies in the RF range an effect called the "skin effect" starts to become significant, current flow restricts itself to the skin of the conductor and the wire resistance rises. Stranded wire offers more skin and thus reduces the wire resistance again.
Can you unlock your car from under the hood?
Some cars can be unlocked from under the hood if the center console for the central locking has its wires in the hood. The unlock wires are usually have a (-ve) current and that means that if you hook one switch wire up to chassis earthing wire and the other to the unlock wire it can unlock all the doors.
What are the main parts of three phase motor?
Wire, bearings, rotor and stator.
Can you wire a Dayton electric motor to run backwards?
Yes, just reverse the start winding circuit.
What is rod earthing?
It is the installation of ground rods at a service entrance distribution to bring the relative resistance to ground to be within 5 ohms of the utility's distribution network. This grounding system is then connected to the service distribution with a calculated size wire and connected to the distribution at a point within the distribution panel, where the service neutral wire joins the neutral bus bar.
