The amount of voltage produced in a battery is determined by the types of chemical reactions occurring within the battery and the materials used for the electrodes. The voltage is also affected by the number of cells in the battery, with multiple cells in series increasing the total voltage output.
what determines the amount of voltage produced by a voltaic cell?
The electrochemical cell develops voltage based on a difference in the internal half cell potential. Each half cells produces a chemical reaction which in turn produces a voltage that is affected by the concentration of reactants as well as the type of reactants within each.
Provided the charging system on the mower engine is operational, a small amount of charging voltage will be supplied to the battery during use.
It's not the amount of wind, but the design of the generator, that decides what voltage is produced. The amount of wind will determine the power produced.
There will be zero amount of heat produced as voltage is just a potential waiting for a load to be connected.
Charging is due to transfer of electrons from one body to another body. Electrons have mass, therefore, mass increases in the case of negatively charged body and decreases in the case of positively charged body.
Changing the temperature increases the change in energy.
It doesn't, a lemon has more voltage than an apple because a lemon has a higher amount of acidity. The more acidity a fruit has, the more voltage it has. [NEEDS CORRECTION] (Acidity in foods does NOT correlate to the amount of voltage produced. See University of Illinois, Physics Department {Q & A: Fruit Batteries | Department of Physics | University of Illinois}.)
Voltage is potential measured by amount of charge or free electrons available to do work. Your voice can generate a pressure wave that can move a diaphragm in a microphone and produce a small voltage which can then be amplified. The type of transducer will determine the voltage which is typically in the millivolt range.
What amount of voltage is supplied by an ordinry cell?
Power = V*I Power = (V) * (C*dV/dt) To store more / less power / charge, charge the capacitor with a greater / smaller voltage (make sure the cap is rated for at least as much as the voltage you are charging from, though).
