What else can I help you with?
Is it all right to cover electric wires with insulation in attic?
Yes as long as they are in a romex style wire. Like 12-2 for example. Which is individual wires incased in an outer jacket. You should never have just single wires running in the attic unprotected or anywhere for that matter. Individual wires must be in a conduit. And any splices should be in a box.
What is the meaning of A2xwy in cable?
Aluminium conductor. XLPE. Nonmagnetic armour, PVC outer sheath
What terminals of a rheostat do you connect to?
A rheostat typically has three terminals: two are connected to the resistor element, and the third is the wiper that moves along the resistive track. To use a rheostat, connect one of the outer terminals to the power source and the other outer terminal to the load. The wiper terminal can then be connected to adjust the resistance in the circuit, allowing for control over the current flow.
What causes signal attenuation in copper cables?
Signal in a copper wire is simply continuous electric current (commonly referred to as electricity), whether alternating current (AC) or direct current (DC). It is not different than the electric power transmission lines that carry electric energy (or power) from power plants to distribution companies and houses.Continuous electric current is the net motion of free electrons that are a part of the atomic structure of every conductor (i.e. metal). In the absense of an electric field, free electrons are in random/chaotic/thermal motion within the conductor, i.e. they are moving randomly and very fast. When an electric field is applied, they start moving under the influence of the applied electric field (i.e. in a net direction), extremely slowly compared to their random motion, but moving nonetheless. This net motion of free electrons is what is referred to as "continuous electric current".If signal is continuous electric current, and continuous electric current is the net motion of free electrons, then signal attenuation is fading of this net motion.What resists to the net motion of free electrons is the fixed atoms on the lattice structure. The "flowing" free electrons collide with fixed lattice atoms and cause Ohmic heating (a.k.a. Joule heating). This explains the resistance of the cable, which is the reason of signal attenuation. As the signal travels on the cable, the voltage level will decrease due to "copper losses" (i.e. ohmic heating). Resistivity increases with length (and decreases with diameter), therefore the longer the cable, the higher the resistance (and attenuation).Near-field electromagnetic fields around a current carrying wire traps the free electrons to the outer shell of the wire. This is referred to as "skin effect". This effectively decreases the cross-sectional area, which in turn increases the resistance, and which in turn increases the signal attenuation. Skin effect becomes more effective at higher frequency signals flowing through the wire. Therefore, higher frequency signals flows through a higher resistance and thus gets attenuated more.Note that fading (i.e. attenuation) of the signal is not the only problem in signal transmission. When a signal is sent, it should arrive at the load (i.e. destination) above some treshold power (i.e. not attenuated too much), and it should arrive undistorted (i.e. not interfered with too much). These are the two concerns:- attenuation- interference.Reactance of the conducting medium (i.e. the cable used) or external electromagnetic fields can interfere with the signal. Cable's reactance comes from capacitance and inductance of the multiple wires isolated (to a degree) from each other within the cable.That's it for now, my friend ;]t
What protection is required when cables pass through holes in metal work?
A protective bushing has to be installed so that the outer sheath of the cable is not damaged during the installation.
Which side the Black stone placed on Kaaba?
it is placed in outer side of kaaba
Were there electric fences at the concentration camps?
Yes, the outer fences had electric currents.
Outer electric shell of an atom?
Valence shell
Main reason for grounding the outer shell of an electric fixture is to what?
The main reason for grounding the outer shell of an electric fixture is to prevent electric shock in case of a fault within the fixture. Grounding directs any excess electricity to the ground, keeping the outer shell safe and reducing the risk of electric shock to anyone touching it.
What criteria are the planets placed into either the inner or outer groups?
Gas giants (for the outer planets), versus rocky planets.
How did the hubble telescope get in outer space?
It was placed in orbit by the space shuttle, in 1990.
If a house has plastic vapor barrier on the inside walls and a foil barrier on the exterior of the house should you remove the existing old outer foil when residing?
Unless your home is heated by electric baseboard you may take it down if you wish. However the foil has reflective heat values, which means it reflects out the heat from the sun in the summer and reflects in the heat in the winter.
What is motor housing?
The outer casing of an electric motor, as in a starter, wiper motor etc.
What is a motor housing?
The outer casing of an electric motor, as in a starter, wiper motor etc.
Should you put baseboard heaters on an outside wall instead of an inside wall and why?
Outside wall is going to be the coldest, has the windows that let cold in. For comfort, you want the heat on the outside wall. ( To add to my fellow compatrons statement ) You should consider placing them under major window areas on outer walls with major drafts through the windows as well. Windows are one of your very largest areas to deal with in heat load calculations and should always be adressed with vigor for drafts.
Which two spheres can energy be transferred by conduction?
Energy can be transferred by conduction between the Earth's lithosphere (solid outer layer) and the atmosphere (gas layer). Another example is the transfer of energy by conduction between a hot electric stove and a pot placed on it.
What is the difference between electric charge and ion?
An electric current goes through an electric circuit, if it is closed.
