How do you calculate the power used by a component when the potential difference is measured as 2.5volts and current is 0.2?
Littleeinstein
You need to know the resistance. Ohm's Law: Current = Voltage (in volts) divided by resistance (in ohms).

What is the potential difference measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
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.
What is the electrical unit of potential difference?
Potential Difference is measured in Volts
What is force measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
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 kind of difference is measured in volts?
Volts are a measure of electric potential difference.
What is used to measure potential difference?
A Volt meter is used to measure potential difference (a.k.a. voltage). Potential difference is measured in units called: Volts (V).
How is the potential difference across a resistor measured?
by using voltmeter
What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt
What is the definition of potential defference?
The difference, measured in volts, in electric potential between two points.
