You need to know the resistance. Ohm's Law: Current = Voltage (in volts) divided by resistance (in ohms).

How is the potential difference across a resistor measured?

by using voltmeter


What is sensitivity of a potentiometer?

Sensitivity of potentiometer means~ smallest potential difference that can be measured with the help of it.


What do you use to measure electricity?

In an electrical circuit there is a flow of electrons. The flow is induced by the creation at a production station, battery, or other supply of an "Electromotive Force (E)". The size of the electromotive force is measured in "Volts". The rate of flow of the electrons through the circuit is called the "Current (I)". Current is measured in "Amperes". The typical conductor for transporting electrons through a circuit is wire and the smaller the diameter of the wire the more the "Resistance(R)" to the flow; the larger the diameter, the less the resistance. Resistance is measured in OHMS. Definitions of volt, ampere, and ohm: 1 volt: Electromotive force required to send a current of 1 ampere through a system in which the resistance measures 1 ohm. 1 ampere: Rate of flow of electrons in a system in which the electromotive force is 1 volt and the resistance, 1 ohm. 1 ohm: Resistance offered by a system in which the electromotive force is 1 volt and the current, 1 ampere.(Found at http://www.tpub.com/content/engineering/14069/css/14069_52.htm)


Why is voltage also called potential difference?

Your question should really be the other way around! Technically, the correct term is 'potential difference'. Since this is measured in volts, over time it has also become known as 'voltage'. A similar thing has happened, but to a lesser extent, with 'power' which, being measured in watts, is often referred to as 'wattage'.So, 'voltage' is simply another word for 'potential difference'. Originally, it meant 'potential difference expressed in volts' but, these days, it applies to microvolts, millivolts, volts, kilovolts, or megavolts!Take care, however, not to confuse 'voltage' and 'potential'. These are different, and voltage should never be used when you mean potential.

The potential difference across component R is measured as 1.0v and the current through it is 0.08a calculate the resistance of component R?

V=IR-->R=V/I R=1.0/.08=12.5 ohms


Potential difference across component R is measured as 1.0v and the current flowing through R is measured 0.08a Calculate the power used by R when the potential difference across the component is 2.5v?

V=IR R=V/I so the resistance of R is 1/0.08=12.5ohms. I=V/R so when V=25, the current =25/12.5=2A Power = IV = 2*25 = 50W =)


What is the potential difference measured in volts?

'Force' isn't measured in volts. Potential and potential difference are measured in volts.


How is a voltmeter connected in a circuit to measure electrical potential difference?

A voltmeter is connected in parallel to the component or circuit being measured to measure the electrical potential difference, also known as voltage. This allows the voltmeter to read the voltage across the component or circuit accurately.


What is force measured in volts?

'Force' isn't measured in volts. Potential and potential difference are measured in volts.


How do you calculate the potential difference in an electrical circuit?

The potential difference in an electrical circuit is calculated by subtracting the voltage at the starting point from the voltage at the ending point. This difference is measured in volts and represents the electrical energy per unit charge.


What is the device used to measure electrical potential energy?

A voltmeter is typically used to measure electrical potential energy. It is connected in parallel with the component or circuit being measured to determine the voltage difference or potential between two points.


What does a voltmeter do and how is it used to measure electrical potential difference?

A voltmeter is a device used to measure the electrical potential difference between two points in a circuit. It works by connecting the voltmeter in parallel with the component or circuit being measured. The voltmeter then displays the voltage difference in volts, allowing the user to determine the potential difference between the two points.


What are the differences between voltage and potential difference?

Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.


Is voltage measured in volts?

Voltage, along with electric pressure, electric tension, and electrical potential difference is measured in units of electric potential. This can be joules per coulomb or volts.AnswerFirst of all, there is no such thing as a 'voltage difference'. Voltage is already a 'difference', as it is an alternative name for 'potential difference'! 'Voltage difference', therefore, would mean 'potential difference difference', which makes no sense!The unit for potential and potential difference (voltage) is the volt, which is equivalent to a coulomb per second.


What instrument measures electric potential?

A voltmeter is the instrument that measures electric potential. It is typically connected in parallel to the circuit or component being measured to determine the voltage difference between two points.


What kind of difference is measured in volts?
