V=IR
V-voltage
I- current
R- resistance offered by the circuit board
(can me measured using miltumeter)
AnswerThe ratio of voltage to current is called resistance. If this ratio is constant for changes in voltage, then the circuit is described as being 'linear' or 'ohmic', and it obeys Ohm's Law. If this ratio varies for changes in voltage, then the circuit is described as being 'non-linear' or 'non-ohmic', and it does not obey Ohm's Law.Most loads and electronc devices are non-ohmic -that is their resistance varies with changes in voltage- which confirms that Ohm's Law is not a universal law, but one that applies only to certain types of load and, then, under specific conditions.

What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship between voltage and current in an inductive circuit?
Current lags voltage in an inductive circuit. The angle by which it lags depends on the frequency of the AC, and on the relative size of the inductance compared to the resistance in the circuit.
What is the relationship between the voltage output at the interface and the voltage across the series and parallel circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
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 phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
What is voltage error circuit and current error circuit?
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
What is a term for the relationship of voltage current and resistance in a simple electrical circuit?
Ohm's Law. According to Ohm's law V = iR where V is voltage (usually measured in volts) between two points of the circuit i is current (usually measured in amperes) between two points of the circuit R is resistance (usually measured in Ohms) between two points of the circuit.
What is meant by lagging and leading circuit?
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
Why does a ac voltage applied across a load resistance produce alternating current in the circuit?
Because V = I x R or Voltage = Current x Resistance. Since resistance is linear there is a linear relationship between Current and voltage. If you have DC voltage you have DC current and if you have AC Voltage you have AC current. Note that there is a linguistic recognition of this relationship in that the voltage is described in terms of the current.
