How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
How do you get negative voltage from transformer?
The term, 'negative voltage', refers to its direction and has nothing to do with 'negative' in the 'charge' sense. It's used to indicate the direction in which a voltage is acting in relation to another voltage ('positive' if acting in the samedirection; 'negative' if acting in the opposite direction). So your question is confusing: 'negative' in relation to what?
Why 555 IC is called a timer?
Change as time from low to high voltage and opposite
Does Kirchhoff current law and Kirchhoff voltage law depend on the relationship between current and voltage in a resistor?
Kirchhoff's Voltage and Current Laws apply to circuits: series, parallel, series-parallel, and complex.If your circuit comprises just a single resistor, then they still apply. For example, the voltage drop across a single resistor will be equal and opposite the applied voltage (Kirchhoff's Voltage Law), and the current entering the resistor will be equal to the current leaving it (Kirchhoff's Current Law).
Why is the internal resistance of a voltage source made to be low?
When a voltage source, such as a battery or a generator, is on open circuit -in other words, when it is not supplying a load- the voltage appearing across its terminals is called its 'open circuit voltage' and corresponds numerically to its electromotive force.However, when the voltage source supplies current to a load, that current also passes through the voltage source itself. This causes an internal voltage drop, which is the product of this current and the voltage source's internal resistance. This voltage drop acts in the opposite direction to the electromotive force and reduces the source's terminal voltage. This internal voltage drop will increase, of course, if either the load current increases or the internal resistance increases.So, in order to keep that the source's internal voltage drop is as low as possible, its internal resistance must be as low as possible. In the case of a battery, the internal resistance is due to the ionic resistance of the electrolyte/plates, whereas in a generator it is due to the resistance of the windings.
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
What voltage is DC?
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.
What does the voltage across a inductor do?
voltage across inductor create a flux. because of variation current developes an opposite emf.
Current ratio is opposite than voltage ratio in transformer?
Yes
Do you add electrical supply voltage and induced voltage of a coil to get total voltage on the coil?
The induced voltage acts to oppose any change in current that is causing it. So, if the current is increasing, then the induced voltage will act in the opposite direction to the supply voltage; if the current is decreasing, then the induced voltage will act in the same direction as the supply voltage.
Which law says voltage increases current decreases?
Ohm's law says the opposite.
What direction does dc Voltage travel in?
It travels from negative to positive. The opposite of what you might think.

What unit of measurement describes the potential that separated opposite charges have for doing work if they are released to fly together?
voltage
Why voltage leads in Inductor?
Maximum induced voltage occurs when the current is changing at its greatest rate -this occurs when the current passes through zero. Since this voltage acts to oppose current flow, this maximum voltage acts in the negative sense when the current is acting in the positive direction. Since the supply voltage is equal, but opposite, the induced voltage, it is maximum when the current is zero -so leads by 90 degrees.
Why is alternating voltage induced in the rotating armature of a generator?
The windings of the armature are constantly cutting magnetic lines of force of opposite polarities
Why 555 IC is called a timer?
Change as time from low to high voltage and opposite
