according to ampere's circuital law,magnetic field is directly proportional to the current flowing through the conductor.thus magnetic field can be increased by increasing the current through the conductor,provided the conductor or wire is capable of carrying high currents i.e. it should be of good conductance.

Radar range is the distance of the object from the radar. Radar bearing is the direction of the object in relation to the radar. As radar is primarily used for ranging, the range information may be more important than the bearing.

An example of a real life exponential function in electronics is the voltage across a capacitor or inductor when excited through a resistor.

Another example is the amplitude as a function of frequency of a signal passing through a filter, when past the -3db point.

Bus Clock is based on the System Clock. In other terms Bus Clock is derived from system Clock. Bus Clock is usually half System Clock. (Busy Clock = System Clock / 2)

A diode allows current to pass in one direction only, and has two pins - Anode and Cathode. A transistor is a switch that has three pins - Collector, Base, Emitter, and a current can pass between the collector and emitter if there is a current on the base.

A picture of diodes and transistors can be found here (left to right: diode, transistor, transistor, LED - diode that lights up):

BIPOLAR

A2

It does not stand for anything. It is a maker's designation mark, a throwback from the thermionic tube (valve) days. The letters in front of the number used to indicate the heater voltage and the type of internals (triode, pentode etc)

B used to indicate that it was a semiconductor, not a tube.

There are different designations around the world, for the same equivalent device, American, European and Japanese.

Only if your amp is rated to handle a 1 ohm load. If it's not you WILL... fry your amp.

Volt meter; And 500kV AC voltages are not measured directly - potential transformers, or capacitors are used to step 500kV down to safe voltage levels for measurement purposes (usually 66-120 volts).

A: the gain will be maximum at the open loop configuration and decrease as frequency increases

A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure sine wave.

No, infrared transmitters and receivers are not interchangeable. Each is different. This, though the two might be thought of as being mirrors of each other as regards function.

Statistical multiplexer does not reserve time slots or frequencies. Instead, it dynamically allocates bandwidth only when it is needed.

Firefighters use it to help break open doors in a fire.

A: the rms value will be169 volts add a capacitor and no load 240 volts and the average will be 153 volts

ICs contain lots of transistors, which are made up of P and N silicon.

No and yes. Digital signals are usually square or pulse waves. By Fourier analysis, however, every periodic wave, even a square wave, is the summation of some series (often infinite) of sine waves.

it controls the speed. when the diode is busted it gains into fullspeed

Resistors, capacitors, inductors, diodes are all passive components.

Internet Hacking. It could hurt you computer and even lead to viruses. Be carefull for hackers out there. Examples: Runescape,Ourworld,Facebook,Yahoo and More.

Chances are good the capacitor is toast and needs to be changed.

we will be out out of coil wire

A ceiling rose is a decorative molding that is installed around the electrical box that a luminaire (light fixture) is attached to. Ceiling roses were popular in the early 1900's. You can still find them in home improvement stores, now days they make cheaper ones out of foam instead of the traditional wood.

These things lead to us overestimating our intuition.
