What ways can voltage be produced?
Voltages are produced by converting one form of energy into electrical energy. Mechanical energy can be converted into electrical energy (voltage and current) by moving a magnet or magnetic coil in proximity with a stationary coil, connected to an electrical circuit. A voltage can also be produced with a chemical reaction. Batteries and fuel cells convert energy in specially designed cells, where a chemical reaction causes a voltage to exist across two electrodes implanted at two different parts of the cell. A voltage can be produced by the interaction of light on a photocell. The photons of light interacting with atoms in the photocell, cause an electron to be ejected. The special design of the photocell causes this to occur in such a manner as to produce voltage across the cell. A voltage can be produced by subjecting a thermocouple to differential temperature. A thermocouple is a relatively simple device composed of two dissimilar metals, joined together at what is referred to as a thermal junction. If one side of the junction is warm, relative to the other side of the junction, a voltage exists across the junction.
Difference between power and furnace transformer?
Power transformer is used step up or down the voltage for the electricity transmission while furnace transformer is used to melt the metals and ores in the electric furnace.
What are the methods of producing emf?
Presently, there are six known methods for producing a voltage or electromotive force (emf). Some of these methods are more widely used than others, and some are used mostly for specific applications. Following is a list of the six known methods of producing a voltage. 1. FRICTION - Voltage produced by rubbing certain materials together. 2. PRESSURE (piezoelectricity) - Voltage produced by squeezing crystals of certain substances. 3. HEAT (thermoelectricity) - Voltage produced by heating the joint (junction) where two unlike metals are joined. 4. LIGHT (photoelectricity) - Voltage produced by light striking photosensitive (light sensitive) substances. 5. CHEMICAL ACTION - Voltage produced by chemical reaction in a battery cell. 6. MAGNETISM - Voltage produced in a conductor when the conductor moves through a magnetic field, or a magnetic field moves through the conductor in such a manner as to cut the magnetic lines of force of the field.
What is the role of thermocouple?
Thermocouple is a heat sensing device.It is made up of 2 dissimilar metals twisted/joined at one end called a junction and that is made Hot and the other end or tell end is cold (may be at 0 degree C). then a voltage is developed accross the two dissimilar metal, this principle is called SEEBECK EFFECT.The voltage developed is directly propersional to the difference in temperature.
How does a lemon make electricity?
A battery is a simple mechanism that consists of two metals in acid. The zinc and copper of the nail and copper hooks become the battery's electrodes, while the juice of the lemon serves wonderfully as the acidic conductor needed to help these two metals work together, thus creating power. The negatively charged electrons flow through the nail to the calculator, providing the power to make the calculator work. They then flow through the copper wire back to the positively charged hook to create an electronic circuit. The acidic lemon juice serves as the conductor that allows the electrons to flow in this way.
What is a question for a lemon?
One possible question is "How does the voltage of the battery change if different combinations of metals are tried for the two electrodes?".
What is the voltage of a pear?
If you are referring to a 'fruit cell' then, in common with all cells, the voltage is determined by the materials from which the electrodes are made -not by the fruit itself. The further apart the metals are on the 'electrochemical series' of elements, the higher the resulting voltage -so, for copper and zinc, the voltage will be about 1.1 V.
Which combination of metals do you think will give the highest voltage copper and lead or zinc and lead?
How do we get lead?
What are two pieces of different metals that are in contact with electrolytes in a battery?
They are the two electrodes: anode and cathode.
What are the two pieces of difference metals that are in contact with electrolytes in a battery?
They are the two electrodes: anode and cathode.
What group in the periodic table are used for electrodes or catalysts?
These are the platinum metals.
What are the two pieces different of metals that are in contact with electrolytes in a battery?
These are the electrodes.
What materials are needed to produce an electrochemical cell?
An electrochemical cell requires two different electrodes (ussually metals) and an electrolyte. Just so you know, i copied this statement straight out of a textbook ;)
What influences the amount of voltage that comes out a fruit?
The voltage of any electrochemical cell is entirely dependent on the two different electrode materials, not the type of electrolyte.Take the same electrodes and put them in anything containing an electrolyte: e.g. any fruit, a potato, salt water, baking soda solution, vinegar, and you will get the same voltage from the cell.The relevant property of the electrode materials is called electronegativity.
What allows electrons to flow between electrodes in an electrochemical cell?
The difference in reactivity between two metals is what causes the electron flow, or voltage. It is facilitated by setting up a Galvanic cell, with two electrodes in solution connected by a copper wire (for electron flow) and a salt bridge (for balancing charges between electrodes.)
What part of a battery composed of two different type of metals?
i believe it's electrodes. you may want to double check. It's definetley electrodes...I double checked!! Tee got a 100% its electrodes
