Electrical Cords & Plugs: A Repairing Guide
Author: pvyas
If the plugs or cords are sparking, just unplug the appliance and cut the power to be safe and secure because it can cause fire leading to health and wealth hazards. After unplugging wait for some time and let the plug cool for some time. Then check the plug, cord and outlet to see if they are damaged. If as such then take it to the servicing center or replace with a new one.
Replace the plugs if :
* If an electrical plug is cracked it should be immediately replaced.
* If the plug is discolored it should not be used further.
* If the electrical plug becomes warm when the appliance is on, it means it is not functioning properly and it is the right time to replace it.
* Replace the plug if it has badly bent contacts.
What make the cords and plugs non-functioning?
Heavy usage and age are the two main reasons that take their toll on consumer appliances specially on cords and plugs. Appliances you use most frequently are the common victims, such as irons, blow dryers, toasters, lamps, and refrigerators. Apart from that the vintage model appliances also wear out early.
Choose the right type of plug for appliances
Now if you have planned to buy a new cord for an appliance, it is of utmost importance to get the proper type for the appliance. We will discuss here three basic type of electrical plugs:
Terminal-screw Plugs: In these plugs, the wires attach to screws inside the cord body. These plugs are usually found on older appliances. Often they have a removable insulating disk covering the terminals and wires. Newer plugs have rigid insulating barriers.
Self-connecting Plugs: Small appliances like lamps mainly use self-connecting plugs. The prongs clamp onto the wires of the cord, and an automatic connection is made.
Three-prong Plugs: These plugs come with larger appliances like refrigerators, washers, dryers, and power tools. They have a prong that grounds the appliances.
Replacing 240-volt Plugs
Replacing electrical cords and plugs on a 240-volt appliances such as a dryer or other large appliance needs special attention. You need to purchase a pigtail cord with a plug molded to it. If the appliance or the pigtail cord is not color-coded, in that case first attach the central wire of the pigtail to the center terminal screw on the appliance. Afterwards connect the remaining wires to the other terminal screws.

what is the diference between electrical energy and magnetic energy?
HOw do you add them to get a sum total?
Volume required to store electrical energy in a uniform magnetic field?
How much volume is required to store 1.3 * 10^6 J of electrical energy in a uniform magnetic field with a magnitude of 0.6 T?
magnetic energy electrical generator?
first of all i have heard about many magnetic electrical motors i am slightly skeptical. I have an idea about making one could there be two magnets in a vacuum sealed container. Each one repelling and attracting in turn pulling a charged object back and forth creating mechanical energy then converted into electrical energy. First of all i am a bit of a layman and i am only interested i do not know much about physics as i would like too, as you can tell . Secondly, i do not know how this charged object could turn its constant movement into efficient mechanical energy. i was thinking that it could compress air? some how. Then the compressed air could be turned from Mechanical into electrical energy though an induction motor or generator.
Again thanks for the advice and help and sorry for the strange wording of the question .
no silly answers
how can i convert electrical energy into magnetic energy?
How is electrical energy converted into magnetic energy?
The energy density of an electric field, in units of energy per unit volume, is one half of the dot product of E and D. In free space in SI units this is just:
eps0 * E^2 / 2
where eps0 is the permittivity of free space.
Similarly, the energy density of a magnetic field is one half of the dot product of B and H. In free space in SI units, this is just:
B^2 / (2 * mu0)
where mu0 is the permeability of free space.
These quantities can be added together to obtain the total electromagnetic energy stored in static fields.
Note that in a material, E and D are not necessarily parallel, nor are B and H. Even an internally isotropic and homogeneous “ideal” dielectric can produce a D vector non-parallel to E, once you account for the geometry of the object, so measuring the electric field density in an object of arbitrary shape can be challenging. An exactly parallel analysis applies for magnetic fields in materials with a relative permeability greater than 1.
It is not. It’s the other way around actually. Magnetic energy changes into electrical energy by way of rotation or generation.
The energy density of a uniform magnetic field is
e = B²/(2*µ0)
The total energy is e*V, so
V*B²/(2*µ0) = 1.3*10^6
V = 1.3*10^6*2*µ0/B²
µ0 = 4*π*10^-7
V = 9.07 m³
A solenoid can move alternately, as in a doorbell. You can also use a Stirling engine to produce reciprocation, which is being studied now in several places, with the motion driving a linear alternator.
Note that the moving object does not have to be charged. A piece of soft iron works well.
The output of a linear alternator is alternating current, so you don’t need to compress air. I’m working on such a device.
coil a long insulated copper wire around an iron nail
join the ends of wire to a battery and switch it on the iron nail will behave as a magnet
.if you put hard iron rod in place of nail and then switch on the circuit
then iron rod will became a permanent magnet.
so in this way you can convert electrical energy to magnetic energy
