Is volts measured by electromotive force?
volts abbr (V)
Unit of emf?
My physics teacher wrote out homework answers for us. On a few EMF problems, he has the EMF unit listed as Weber. On others, he has it as volts. I have a quiz tomorrow so I need to know which SI unit i'm supposed to use. Thanks! Few side notes: the formula we're using is E=delta I (subscript B) /delta t . There was no change in the formula for the different problems or what not. and somehow weber / time went to volts, other times it didn't. BY: VOLT
How are emf measured?
emf in volts
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.
While discharging which is greater TPD or EMF?
EMF is greater
What is a another unit of measurement for an EMF?
a british band
What unit measures EMF?
EMF stands for Electro-Motive Force, commonly known as Voltage, measured in Volts.
What are the differences between potential difference and emf?
Potential difference is the difference in electric potential energy between two points in a circuit, while electromotive force (emf) is the total energy provided per unit charge by a battery or voltage source. In other words, potential difference measures the voltage drop across a component in a circuit, while emf represents the energy per unit charge supplied by the source.
Is volts measured by electromotive force?
volts abbr (V)
Three similarities between pd and emf?
Both emf and pd have the same unit. namely volt Both have the same definition. It is the work performed in moving unit positive charge right from one point to the other against the electric field. Both are got by the product of current and resistance. But emf is the pd across of a cell or source when it is not in action. So emf is slightly greater than the pd in the circuit as there may be a little bit of internal resistance.

What is emf in physics?
EMF, or electromotive force, is a measure of the energy provided by a source (such as a battery) to move a unit charge around a closed circuit. It is responsible for driving the flow of electric current in a circuit. EMF is measured in volts.
Is lenz law used to find induced EMF's?
Yes, Lenz's law is used to determine the direction of induced electromotive force (EMF) in a circuit. It states that the direction of the induced EMF in a conductor is always such that it opposes the change in magnetic flux that caused it.
What is the SI unit for direct current?
The SI unit for direct current is the ampere, symbolized as A.
How are emf measured?
emf in volts
Why emf of battery driving potentiometer is greater than emf of the cell to be measured?
Bcoz the emf which is to be measured is less than emf of driving cell....
