i.e normally we have various sensors to measure the voltage but my doubt is, how the voltage circuit measures the voltage i.e i need the detail for each and every unit.... If anybody know means plz tell to me.....
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
Voltage Rise : The energy added to a circuit. Voltage drop: The energy removed from the circuit.
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
There is no particular benefit for having a higher open-circuit (or 'no-load') voltage. In fact, an ideal voltage source would have no internal resistance and, therefore, its open-circuit voltage would be identical to its closed-circuit voltage.
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
A circuit is designed to work at a specific voltage and that voltage only.
Voltage drop in an electrical circuit occurs when there is resistance in the circuit, causing a decrease in voltage as the current flows through the components. This drop in voltage is proportional to the amount of resistance in the circuit, following Ohm's Law (V I R).
when a resistor is connected in a circuit it drop some voltage across it.when a circuit have large input voltage then by using a resistor of suitable value we get the desired voltage.
The essential circuit of a voltage divider, also called a potential divider, is:
Voltage is what drives the current to flow in a circuit, so it provides the potential energy to do work. The current then carries that energy through the circuit to power devices or perform work, such as generating heat or light. Both voltage and current are essential for work to be done in a circuit.
A series circuit will work if there is a closed path through which the current can pass, and a voltage source. Otherwise it won't.
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
In a series circuit, the potential voltage across the circuit components adds up to the total voltage of the circuit.
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
A voltage divider is a circuit that uses two or more resistors to divide the input voltage into smaller voltages across each resistor. The voltage across each resistor is proportional to its resistance compared to the total resistance in the circuit. This allows for distributing the input voltage across multiple resistors in a controlled manner.
The amount of work done by an electric circuit is equal to the product of the voltage applied to the circuit and the total charge that flows through it. Work done (W) = Voltage (V) x Charge (Q) = V x Q.
An electrical circuit must be complete i.e it must form a closed loop,for it to work. Current only flow if the circuit is complete. A complete circuit is one that consist of a Voltage source, a consumer like a bulb and conductors. The conductor then connects the consumer and the voltage source together forming a closed loop.
