Frequency in Hertz is a count of cycles per second. So at 60Hz, there are 60 cycles per second. This means there are (60 cycles per second x 60 seconds) = 3600 cycles per minute.
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
It makes AC ( alternating current ) . That's why it's called an alternator. A DC generator would usually be called a dynamo.
In a simple alternating current generator, electrical connections with the rotating coil are typically made using slip rings. These are conductive rings attached to the coil that rotate with it, allowing for a continuous electrical connection with stationary brushes that maintain contact with the slip rings. This setup enables the generated alternating current to be transferred to an external circuit while the coil rotates within a magnetic field.
You need alternating current for a transformer, for DC you would have to interrupt the power supply to make it effectively DC pulses.
For the same bulb, there would be no difference if the AVERAGE power is the same. For DC this is easy....Power = V X I. For AC it is much more complicated, for a purely resistive light bulb, Power = Vrms X I. So for AC the voltage is the "root mean square" of the peaks.

alternating current electricity, or AC current, or AC.
First, the alternating current is filtered through a rectifier diode, that is, a device that lets the current pass only in one direction. This will produce a current that goes only in one direction, but that pulsates. To smooth this out, i.e., to convert it into a relatively uniform current, capacitors are used as "buffers".
AC/DC basically stands for "alternating current/direct current" which is an indication that electricity is changing from an alternating current (e.g. from your wall outlet) to a 'direct current' (e.g. your T.V.). Brothers Malcolm and Angus Young felt that this perfectly symbolised the music they wanted to make (i.e. raw energy, performances driven by power and a sheer love of music).
A 50-cycle process means that in one second, there are fifty complete occurrencesof everything the current will do . . .-- pass through zero increasing-- build up to the maximum positive value and then shrink back to zero-- pass through zero decreasing-- drop to the maximum negative value and then grow back to zero.All of these make up one cycle. All of them occur 50 times every second.
A rectifier is used to convert alternating current (AC) to direct current (DC). The rectifier allows current flow in one direction only, converting the back-and-forth flow of AC to a constant flow in DC circuits.
It's the concept of alternating periods of economic expansion (growth) and contraction (decline) in an economy. These cycles are often referred to as the business cycle and can impact various economic indicators such as employment, inflation, and GDP. Understanding these cycles is crucial for policymakers and businesses to make informed decisions.

<p><p> ADC Converters are those converters which converts continuous quantity to discrete time digital representation.Typically, an ADC is an electronic device that converts an input analog voltage or current to a digital number proportional to the magnitude of the voltage or current. * ADC is converting Analog to Digital,but Rectifiers converts from ALTERNATING CURRENT to DIGITAL CURRENT. ANALOG and ALTERNATING are different concepts. But , Rectifiers are totally different issue, they convert Alternating Current(AC) to Direct Current(DC). They cut the negative waveform from AC wave and make it uni- directional which is called Direct Current(DC) wave.
