Ohm's law: voltage = resistance time current.
P=vi
Power = Current x Voltage x Power Factor
Power Factor ranges from zero to 1 which is a pure resistive load. Basically it is a measurement of the lag in phase between current and voltage.
Q=It, or charge = current x time.
W=VQ, or work done = charge x voltage
Therefore, substituting equation 1 into equation 2,
W=VIt, or work done by a source = the electromotive force or potential difference (also known as voltage) x current passing through the component x time.
Q.E.D
Voltage is directly proportional to current.
The resistance is voltage divided by the current
R=V/I
where I=current
you can reform that equation to make other ones, like
I=V/R
or V=(I)(R)
the connection between voltage and current is that they are both powerful forces!
Voltage is the amount of energy possessed by each amount of current. If resistance is known (and constant), then you can form a proportional relationship, as V = IR.
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
They are proportional to each other with a constant of 1/V, by rearrangment of the formula V = IR.
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
In simple MOSFET current mirror, the load current does not follow a linear relationship with reference current (ie for short channel MOSFET's multiplying factor due to channel length modulation cannot be neglected). But by cascoding the output resistance can be increased and since output resistance follows an inverse relationship with lambda (channel-length modulation parameter), the multiplying factor due to channel length modulation reduces to one and a linear relationship is obtained between reference and load current.
The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).
because current is the ratio of voltage and resistance.
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
This relationship was discovered by Karl Georg Ohm.
Ohm's law gives the relationship between current, voltage, and resistance. The law states that I=V/R, where I is current, V is voltage, and R is resistance. Source: university digital fundamentals
Voltage is the product of current times resistance, V=IR, I is Current and R is resistance. ANSWER: It is a simple ratio of 1:1:1
That is called Ohm's Law.
P=I^2*R where P=power I=Current R=Resistance
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
It's called 'Ohm's Law'.
