a little thing called an ammeter, you clip this onto your circuit and it measures the voltage!xxx ask again

What is open circuit voltage when load is connected?

As load is conected in circuit , so thre is no open circuit therefore there would not be any open circuit voltage.


How to figure out ampreage in a circuit?

For a d.c. circuit, you divide its supply voltage by the resistance of its load. For an a.c. circuit, you divide its supply voltage by the impedance of its load.


Why voltage measured at terminals of battery to which load is connected is always lower than open circuit voltage?

Real-world batteries do not have zero internal resistance. When one connects a load (resistance) to a battery, current begins to flow and the open-circuit potential is divided between the battery's internal resistance and the resistance of the load. Thus, one will measure a lower voltage at the battery terminals when a load is connected, compared to no-load conditions.


Voltage current relation in passive circuit?

in passive circuit it depends on the type of load 1. if the load is purely resistive the voltage and current will be in phase 2.if the load is purely inductive the current lags the voltage by 90 dgree 3.if the load is purely capacitive the currents leads the voltage by 90 degree


Is the open circuit voltage of a solar cell measured under non-illuminating condition?

Well, you should really measure the open-circuit voltage and the short circuit current both under dark and light conditions and then compare them to fully characterize a solar cell. Measuring the open-circuit voltage means measuring the voltage across the cell when no current is flowing (i.e., with a LARGE resistance as a load on the cell). Measuring the short-circuit current means measuring the current when the voltage across the circuit is essentially zero (i.e., with a VERY SMALL resistance as a load on the cell--thus, "short-circuit" current).

How does the voltage across a load is measured in a circuit with alternating current?

The voltage across a load in a circuit with alternating current is typically measured using a voltmeter. The voltmeter is connected in parallel to the load, allowing it to measure the effective voltage or RMS voltage across the load. This value represents the average voltage of the alternating current waveform.


What is difference between floating load and ground load?

In case of grounded load load is grounded and voltage is measured across it. while in case of floating load load is not grounded instead it is connected in feedback circuit.

How to perform a voltage drop test?

To perform a voltage drop test, follow these steps: Turn off the power to the circuit you are testing. Connect the positive lead of a multimeter to the positive terminal of the power source. Connect the negative lead of the multimeter to the positive terminal of the load. Turn on the power to the circuit. Measure the voltage displayed on the multimeter. Compare the measured voltage to the expected voltage drop for that circuit. If the measured voltage is significantly lower than the expected voltage drop, there may be an issue with the circuit.

What is open circuit voltage in a Fuel Cell?

A: All batteries will eventually fail when that occurs the voltage out of then can be zero or higher voltage when new, In that case the battery has failed but if you measure the output it will have a higher voltage because there is no load or open circuit as soon as the load is applied the voltage just disappear this condition is called open circuit voltage


How much load current of an ac?

The load current of an AC circuit depends on various factors such as the voltage of the circuit, the resistance of the load, and the power consumption of the load. It can be calculated using Ohm's Law (I = V / R) or the power formula (P = VI).


What is voltage regulation formula?

Voltage (load) regulation is to maintain a fixed voltage under different load.Voltage regulation is limiting factor to decide the size of either conductor or type of insulation.In circuit current need to be lower than this in order to keep the voltage drop within permissible values. The high voltage circuit should be carried as far as possible so that the secondary circuit have small voltage drop.% Voltage Regulation = (1.06 x P x L x PF) / (LDF x RC x DF)Where:P - Total Power in KVAL - Total Length of Line from Power Sending to Power Receiving in KM.PF - Power Factor in p.uRC - Regulation Constant (KVA-KM) per 1% drop.RC = (KV x KV x 10) / ( RCosΦ + XSinΦ)LDF - Load Distribution Factor.LDF = 2 for uniformly distributed Load on Feeder.LDF > 2 If Load is skewed toward the Power Transformer.LDF = 1 To 2 If Load is skewed toward the Tail end of Feeder.DF - Diversity Factor in p.u
