by Tarun Agarwal 5 years ago What is a Sine Wave Generator and Its Working In electronic and communication applications, a signal that occurs naturally is known as a sine wave. There are numerous electronic devices that use sine waveforms like radio, etc. Usually, the power devices process otherwise generates...
by Tarun Agarwal 5 years ago Difference between Open Loop & Closed Loop Control System The behavior of the system can be determined with the help of a differential equation is known as the control system. So it controls different devices as well as systems with the help of control loops. Control systems are classified into...
by Tarun Agarwal 5 years ago What is Metal Oxide Varistor & Its Working A varistor is also known as VDR (voltage-dependent resistor) is one kind of electronic component. It has VI characteristics that are the same as to a diode. The main function of this component is to protect the devices from high transient...
by Tarun Agarwal 5 years ago What is HRC Fuse : Working & Its Applications The flow of current in an electrical network is within a fixed limit. Once the flow of current in the network crosses the fixed limit, a fault occurs within the network like phase to ground or phase to phase short circuit. When the flow...
by Tarun Agarwal 5 years ago What are the Various Losses in DC Machine? We know that DC motor is used to change the power from electrical form to mechanical form similarly; dc generator is used to change the power from mechanical form to electrical form. The input power in the DC generator is in mechanical...
by Tarun Agarwal 5 years ago What is Transformerless Power Supply & Its Working In general electronic products, the DC power supply converts the AC voltage to a small DC voltage by using a step-down transformer. Switch-mode power supply or step down transformer converts higher AC to lower AC voltage and then to the...
by Tarun Agarwal 5 years ago What is Transformer Oil : Types & Its Testing The oil used in the transformer is a key element to check the physical condition of the unit. In the last five decades in India, there is a drastic change in production technology. The mineral-based oil like transformer oil is frequently...
by Tarun Agarwal 5 years ago What is an Open Loop Control System & Its Working The first control system was invented by “James Watt’s Flyball governor” in the year 17. The main intention of this device is to maintain the engine speed constant by changing the steam supply to the engine. At present, the control...
by Tarun Agarwal 5 years ago What is Voltage Follower : Working & Its Applications Operational amplifiers are frequently used in a voltage follower design. But, this is not the finest arrangement in terms of potential risk & capacitive loading of oscillations. These loads have a huge impact on the op-amp stability...
by Tarun Agarwal 5 years ago Types of Losses in a Transformer and Their Efficiency An ideal transformer is very efficient so they don’t have energy losses, which means the power supplied to the transformer’s input terminal must be equivalent to the power supplied to the transformer’s output terminal. So the input...
