What else can I help you with?
Can back emf in an inductor be in the same sense as emf of source?
yes..only the application is different.
It can be said that pressure and electromative force are the same?
There is analogy between pressure and EMF or voltage. What pressure is to the liquids, EMF or voltage is to electric current. But, of course, they are not the same.
How does the EMF of a battery which is made up of cells in series compare with the EMF of the individual cell?
The EMF of a battery made up of cells in series is equal to the sum of the EMFs of the individual cells. When cells are connected in series, their voltages add up. For example, if you have two 1.5V cells in series, the total EMF of the battery would be 3V.
What happens to emf as a battery is used?
As a battery is used, its electromotive force (emf) decreases due to various factors such as internal resistance, chemical reactions, and depletion of the chemical components that generate the emf. This leads to a reduction in the voltage output of the battery over time as it discharges.
What is the emf of an electrolytic cell made with solid aluminum and silver electrodes?
-2.48
What is the emf of a voltaic cell made with solid zinc and silver electrodes?
+1.56
What is the difference between Counter-electromotive force and back emf?
They are Same for dc motor
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....
What happens to electrical current as voltage is increased?
If everything else stays the same, power increases as EMF increases. (EMF is to volts as power is to watts.)EMF = Electromotive Force.AnswerPower is proportional to the square of the voltage. So, if you double the voltage, you'll quadruple the power... providing everything else stays the same!
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.
A voltaic cell is made of silver and gold electrodes What is the emf of this cell?
1.03 V
