GND full form is ground. it is very commonly used in electrical engineering as a basic concept. It works as a reference point of voltage in circuits and protects the circuit and the person working the circuit. It is a common return path of current to a p
Why measuring voltage is useful Technicians approach most troubleshooting situations knowing how a circuit should customarily perform. Circuits are used to deliver energy to a load—from a small device to a household appliance to an industrial motor. Loads often carry a nameplate that identifies the...
A Voltage Regulator is an integrated circuit that outputs a specified DC voltage. An example of this is a 5-volt regulator, such as theLM7805, which provides a consistent voltage of 5 volts. Voltage regulators are necessary in applications where a certain constant and consistent level of DC vo...
The resistor is a passive device and doesn’t do anything actively to your circuit. It’s actually a pretty boring device. If you add some voltage to it, nothing really happens. Well, maybe it gets warm, but that’s it. But, by using resistors, you can design your circuit to have ...
Voltage is one of the basic parameters that describes the electrical conditions in a circuit - measured in volts which the unit of voltage, it is a key parameter.

What is the Purpose of a Voltage Follower One may ask then, what is the purpose of a voltage follower? Since it outputs the same signal it inputs, what is its purpose in a circuit? This will now be explained. An op amp circuit is a circuit with a very high input impedance. This ...
The voltage dropped by a component accounts for a portion of the voltage generated by the battery. In other words, the work performed by the battery is divided up among the components in the circuit. We can intuitively recognize that driving a given amount of current through more resistance w...
