Insulator: A material that has high electrical resistance and is therefore a poor conductor of electricity.
Integrated Circuit (IC): A type of digital circuit in which transistors, diodes, resistors and capacitors are constructed on a semiconductor base.
Light Emitting Diode (LED): A type of diode that generates light when current flows through it.
Ohm’s Law: The relationship between voltage, current and resistance.
Ohm (?): The unit of measure for resistance.
Printed Circuit Board (PCB): A board in which components are connected using a thin coat of conductive material “printed” on the board instead of wires. It is used for mounting electrical components.
Resistance: The electrical friction between an electric current and the material it is flowing through that causes electricity to be dissipated as heat.
Resistor: An electrical component used to introduce resistance into a circuit.

what is ohm,s law ?
Jeevan,
Ohm’s Law establishes the relationship between voltage, current and resistance in a circuit. In very simple terms it states that the current is directly proportional to the voltage, and inversely proportional to the resistance. For a proper in depth explanation you can look at the Wikipedia entry for it: http://en.wikipedia.org/wiki/Ohm's_law
