What would happen if there was only positive electrodes in a circuit?
Nothing. The reason a circuit works is that there is an imbalance between the positive and negative (cathode and anode) ends of the battery. two positive ends wouldn't move anything.
What would happen if you charge a 1.5 volt battery on a varying DC input in the range of 12-40 volts?
Batteries have internal resistances built in them, a guideline that is carefully studied in battery manufacturing. Higher voltage over resistance implies higher power and hence heat build-up, huge build-up will weaken the battery structure by volume expansion. The aggressive charging/discharging will cause the metal ions to deform the cathode/anode in the battery respectively. The motion of ions in the battery, cathode to anode or visa versa, is intrinsic to the charging and discharging operation. If the cathode or anode is deformed, the surface area formed by the deposited de-ionised particle will yield less than intended due to abnormalities in the formation. Charging and discharging again at normal operation modes will not undo the damage done to the structure of anode or cathode. Do not charge any battery type at more 10-15% voltage than you can draw from. Charging at such high voltage compared to Battery voltage would cause battery explosion. The duration of improper charging before battery explosion is dependent on how much pressure is built up in the battery from heat generated by internal resistance and quality of casing that is housing the battery nodes and chemicals. Eventually, metallic gas will seep out of the battery causing acidic skin burns and metallic gas poisoning. Injury from flying battery fragments is possible at such insane charging modes.
What happen when ac supply given to dc relay?
The relay's coil burns open. This is not necessarily the answer. Remember normally when a DC current is used a specific magnetism with a prominent North and South is created by the current carrying coil. If we are to use this magnetism together with another permanent magnet's interaction. a deflecting force results. This deflection can be controlled by a restraining spring and the angle of deflection is often a measure of the current. Now in place of the DC current an AC current is made to pass. The deflection is not shown by the meter as ac will create poles as per its frequency and direction of current flow. Also based on the magnitude of its current is the magnitude of the strength of the coils magnet magnet. Assuming same voltage in both cases the coil need not burn out. The deflection is absent here as polarity keeps reversing several times each second and the average value of the 2 forces cancel each other. In DC this deflection is prominent as the poles remain fixed. In relays there is no permanent magnet. However the AC current fed to relay coil will have a higher impedance in comparison to a DC current. This is because of a phenomenon called self inductance. The self inductance will create a back emf that will restrict the current in the coil. Hence the magnetising of the relay core will not be strong. Hence the relay may not operate at all. In Dc this back EMF is momentary and gradually the current increases to a maximum and stays steady. Hence a DC relay if fed by an AC voltage of same magnitude may not be able to pick up and do the necessary activation.
What will happen if we use current transformer of different rating for each phase in three phase supply?
A current transformer has to have the same ratio as the meter that it drives. Full scale deflection on the meter is 5 amps which equals the maximum allowed current on the phase that it is reading. A different ratio on the CT to meter would show an erroneous reading on the meter depending on the ratio of the connected CT. To keep costs down the meter is common to all three phases and is read by connecting the meter to the phase CT through a three position switch.
What happen when plus ve gate pulse given to reverse baise scr?
You cannot turn an SCR off by reverse biasing the gate. Once it is on (anode to cathode), it stays on until the forward current AND the gate current drops to the required threshold level. That said, you can pulse the anode negatively to turn an SCR off, so long as you don't exceed the reverse bias limits of the device. This is how (photographic) flash devices, for one example, can modulate the duration of the flash.
Where does reduction happen in an electrolytic cell?
cathode
What will be happen if you are using the same metal as anode and cathode?
nothing will happen.
When did Cathode ray tube amusement device happen?
Cathode ray tube amusement device happened in 1947.
What would happen to cathode rays in a vacuum?
Cathode rays in a vacuum would travel until stopped (or deflected by an electromagnetic field).
How do cathode rays form?
Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
What will happen to the soil when put in water?
Float heavier particles will sink
What would happen if you used an alternating current during electrolysis?
the cathode and anode keeps interchanging between each other
Give an example in which the distance traversed by a particle is larger than the magnitude of its displacement in the same time?
This may happen when the particle moves back and forth.
An electrolytic cell is made with zinc and aluminum electrodes Which of the following happen at the cathode of this cell?
Aluminum is reduced. Zinc ions are formed.
What will happen inside the nucleus if there alpha particle radiation?
Two neutrons and two protons will split off from the main nucleus as the alpha particle, leaving a different element.
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What happpens when the anode and cathode touch?
A short circuit occurs. Depending on the potential sparks, fire and other bad things may happen.
