Difference between AC and DC

-
 AC and DC current are the two types of electrical current that are used in different applications. The main difference between the two is the direction of the flow of electrons. In AC current, the direction of the flow of electrons changes periodically, while in DC current, the direction of the flow of electrons is constant.

AC current is generated by devices such as generators and alternators. It is used in most homes and buildings for powering lights, appliances, and other electronic devices. It is also used in power transmission systems to transmit electricity over long distances. The main advantage of AC current is that it can be easily transformed into different voltages using a transformer, which makes it more efficient for power transmission.

DC current, on the other hand, is generated by devices such as batteries and solar cells. It is used in applications such as electric vehicles, electronic devices, and certain industrial processes. The main advantage of DC current is that it is more stable and consistent than AC current, which makes it more suitable for certain applications such as electronic devices.

Another significant difference between AC and DC current is the way they interact with the resistance of a circuit. AC current tends to cause more heating in the circuit due to the changing direction of the current, which can cause damage to electronic devices. DC current, on the other hand, does not cause as much heating, which makes it a better choice for electronic devices.

In summary, AC and DC current are two types of electrical current that have different characteristics and are used in different applications. AC current is used in most homes and buildings and is more efficient for power transmission, while DC current is used in electronic devices and certain industrial processes. Understanding the differences between the two can help in choosing the right type of current for a specific application.

  Difference between Inverters VSI vs CSI VSI (Voltage Source Inverter) CSI (Current Source Inverter) 1. In voltage source inverter input voltage is kept constant. 1. In current source inverter input current is kept constant. 2. VSI is fed from a DC voltage source having small or negligible impedance. 2. CSI is fed with adjustable current source from a DC voltage source of high impedance. 3. DC source in parallel with large capacitor. 3. VSI can be converted into CSI, By connecting large series inductance. 4.Input voltage is maintained constant. 4. The input current is constant but adjustable. 5. An output voltage is independent of load. 5. An output current is independent of load 6. The waveform of the load current as well as its magnitude depends upon the nature of load impedance. 6. The magnitude of output voltage and its waveform depends upon the nature of the load impedance. 7. VSI has slow response than CSI.  7. CSI has fast response than VSI. 8. VSI requires feedback diodes 8. T

Image
  8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers. It consists of are four parallel 8-bit ports, which are programmable as well as addressable as per the requirement. An on-chip crystal oscillator is integrated in the microcontroller having crystal frequency of 12 MHz. Let us now discuss the architecture of 8051 Microcontroller. In the following diagram, the system bus connects all the support devices to the CPU. The system bus consists of an 8-bit data bus, a 16-bit address bus and bus control signals. All other devices like program memory, ports, data memory, serial interface, interrupt control, timers, and the CPU are all interfaced together through the system bus.

why we do not store Ac in battery

-
We do not store AC (alternating current) in batteries because batteries are designed to store and release direct current (DC) electricity. AC electricity has a constantly changing voltage and direction, while DC electricity has a constant voltage and direction. Batteries are made up of cells that contain two electrodes (positive and negative) and an electrolyte solution. When a device is connected to a battery, the electrons flow from the negative electrode, through the device, and back to the positive electrode. This flow of electrons creates a direct current. If AC electricity were stored in a battery, the constantly changing voltage and direction would cause the electrons to flow in different directions and at different speeds, which would damage the battery and potentially cause it to malfunction or fail.
