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.

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)

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.

How does load current varies with the load resistance?

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.


What is the relationship between current and resistance?

They are proportional to each other with a constant of 1/V, by rearrangment of the formula V = IR.


Relationship between resistance and capacitive reactance?

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.


What is the Relationship between power factor and current?

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.


Why is a cascode current mirror better than a simple MOSFET current mirror?

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.

What is the relationship between ohms resistance and amps for current?

The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).


Why there is a relationship between current and voltage?

because current is the ratio of voltage and resistance.


What is the relationship between the voltage and the current when the resistance is kept constant?

Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.


Who discovered the relationship between the electric current and resistance?

This relationship was discovered by Karl Georg Ohm.


What relationship does Ohm's law express?

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


What is the mathematical relationship between current voltage and resistance?

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
