The OHMS LAW is E=IR. Please comment here if there is something wrong.

E= Electromotive Force
I=Current
R=Resistance


     The units used are: Volts for EMF, Amp for I and Ohm for R.


So much for that.

Let's move on into OSCILLATION, our last topic.


         In the case of using a battery to energize a tank circuit, we cannot catch up with the speed at which to recharge the circuit. A Q (transistor) can do the job. It will keep on feeding the TANK circuit and will it it oscillating.

         The poroblem was to keep the frequency stable and the answer was QUARTZ! Quartz Crystal we call it. It can be ground to vibrate at a certain frequency and the beauty of the crystal is that it remains stable in its oscillation even at a wide arange range of temperature. But crystals do not vibrate by itself. Electric current has to be fed into it. PERFECT, it is widely used to keep the frequency of our oscillator steady.

CAN WE TRANSMIT USING A SINGLE Q?   YES!
