Electronics Engineering

A semiconductor is a material whose electrical conductivity properties fall between that of a conductor and that of an insulator.

You need a 6 volt charger. When you buy a charger look for one that monitors the voltage level of the battery while it is charging and when the battery is fully charged it will turn off. Indiscriminate charging of a small battery can easily destroy it. Being left on the charger too long can boil the electrolyte out of the battery. A battery can not recover from this action and it will need to be replaced.

The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.

Radiation from an antenna can be blocked by using a simple sheet of conducting material. Aluminum foil would work. But you'd have to set things up so whatever it is you are shielding is completely in the electromagnetic shadow of the antenna. Metal screen would work, too, but you'd have to make some calculations as regards the frequency of the radiation you wish to block and the size of the openings in the screen. You can see the items in your microwave heating up, but the radiation can't get out. Same principle.

is this in reference to 1080p? that means that the display is 1920 x 1080. or 1,920 pixels wide by 1,080 pixels high. They measure displays by number of pixels, pixel density, and contrast (how dark are the blacks).

ummm a fuse.

E=IR.....So, R=E/I........ E volts diveded by I amps= resistance.... You do the math...

I am sure there are service and installation companies, I don`t know about manufacturers though I believe Dunham/Bush has a plant somewhere in Malaysia.

Capacitors store electrical charge.

Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit.

As time passes the current in the circuit will go down and the voltage of the capacitor will go up - this is because as the capacitor gains more charge it gains more voltage, lowering the voltage across any resistance in the circuit consequently lowering the current in the circuit. When the capacitor is virtually full no current will flow at all and the voltage across the capacitor will equal the DC source voltage. At this extreme the capacitor can be treated as an open circuit, so for low frequency AC (allowing the capacitor to fill up before the current alternates) we can treat the capacitor as being an open circuit.

Technically, it is not an open/closed circuit when it comes to AC because the capacitance will results in a signal lag or lead. However, if the frequency is low/high enough the lag/lead is often negligable.

QDrive is the only company I know which manufactures commercial linear alternators. Visit www.qdrive.com for details. They manufacture linear alternators upto 10 kW. But I guess they are very heavy!

The Umbra Group (www.umbragroup.it) also manufactures linear alternators from 700 Watts to +50 kW. These linear alternators take advantage of the back-drivable nature of ball-screws to amplify the linear input velocity into higher rotary output velocity which is harnessed for electrical power production. Consequently, these units are much smaller and lighter than competing designs.

The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.

A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance.

A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.

The difference is the way the data is separated and transmitted between two points.

In Space Division the data is separated physically i.e. the carrier medium is divided into different channels. This could be by using different wires, waveguides, optical cables, etc, or by frequency i.e. radio channel, carrier frequency.

Time Division uses the same channel in one of the above but different data is given a specific order and location in time for transmission.

e.g. Synchronsation followed by type (a) data, then type (b) data followed by a checksum. The whole process is repeated continuously until transfer is complete.
