An oscillation is a term we could use to refer to a single cycle of a cyclic or repeating motion. Let's just take one example (so we don't run it into the ground) and see how it applies. And we'll use that familiar pendulum clock. The pendulum on a clock will be driven by a spring. We swing the pendulum up, release it, and gravity and the spring do the rest. The spring, as you have guessed, adds just enough energy to offset the friction loss in the system. When we lift the pendulum and release it, it is pulled down (accelerated) by gravity. It passes through a point where it is at the "bottom" of the swing (having achieved maximum velocity), and then heads up on the other side. It's decelerating here under the influence of gravity - that same gravity that accelerated it. I continues to slow, it stops, and then accelerates back down and across the "middle" or "bottom" again. Up it goes to the top of its arc on the other side, and it returns to its starting point. It has completed one cycle of its oscillation. It has performed one oscillation. Simple, and easy.

What are COHO in MTI Radar?
Cohrent oscilator
Changing DC current to AC what does it take to do this?
All you need to do is use a oscilator in the circuit between the DC source and the load, most preferably u can use a static oscilator as used in a household inverter.
What are the applications of hartley oscillator?
hartley oscillators are mainly used in radio receivers. Also note that due to its wide range of frequencies it is the most popular oscilator
What is local oscilator?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)
What is the working principle of a colpitts oscilator?
The principle of LC tank ckt. which produces 180 deg phase shift the loop gain AB=1 in hartley oscillator are used 2 inductors and 1 capacitor.
How do you convert 220 volts 50 Hz to 110 volts 60 Hz?
Converting the voltage isn't a problem, but converting the frequency could require some additional support electronics. To convert 220 volts to 110 volts, all you need is a transformer with a 220 volt primary and a 110 volt secondary. To convert the frequency, you'd need to come up with either a frequency converter or design and build one.
