Place a voltmeter across the two points in the circuit you want to measure, and measure it. Be sure to know the expected voltage so that you can take appropriate safety precautions, and know the impedance of the circuit so that you can choose a voltmeter with a high enough internal impedance that it will not significantly affect the circuit.
What else can I help you with?
How do you measur ampere?
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!
What is the potential voltage across the circuit components in a series circuit?
In a series circuit, the potential voltage across the circuit components adds up to the total voltage of the circuit.
How is voltage spread out in series circuit?
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
What is the voltage in a series circuit where multiple components are connected in a series, known as series circuit voltage?
In a series circuit, the voltage is the same across all components connected in a series. This is known as the series circuit voltage.
What is Voltage rise?
Voltage Rise : The energy added to a circuit. Voltage drop: The energy removed from the circuit.
What is the applied voltage to a resistive capacitive circuit?
this is the amount of voltage a circuit can hold.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
What are the 2 rules for the voltage and current in a series circuit?
In a series circuit, the current remains constant throughout the circuit. The voltage across each component in a series circuit adds up to the total voltage of the circuit.
What type of circuit in which voltage is constant?
A mercury battery will provide constant voltage. A voltage regulator circuit will also.
What is voltage error circuit and current error 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.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What benefit is there for getting higher open circuit voltage?
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.
