Voltage, which belongs to the concept of circuit. For a dry battery, the voltage is 1.5V, that is to say, the "potential difference" between the positive and negative poles is 1.5V, that is, the potential at both ends of the battery is different and high and low. When an external circuit is connected, electricity can flow from the end with high potential to the end with low potential to form a current, just as water flows from high to low.
Current refers to the movement of charged particles. Charged particles can be electrons, ions, or holes in semi layered materials. The moving medium can be solid, liquid, gas, or in vacuum. The definition of current is "the amount of electricity passing through per unit time", so it depends on the speed of time. Common currents include: conductor current, current of lightning breaking through air, current in vacuum devices (electronic tube, various electric vacuum light sources, traveling wave tube of radar, magnetron of microwave oven). If you wave a brush in the air after friction and electrification, it is also a kind of 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 he relationship between voltage current and resistance called?
That is called Ohm's Law.
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
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.
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
What is the relationship between voltage and current as shown in the graph of voltage vs current?
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
What does the current vs voltage graph reveal about the relationship between current and voltage in the given circuit?
The current vs voltage graph shows that there is a linear relationship between current and voltage in the given circuit. This means that as voltage increases, the current also increases proportionally.
What is the relationship between the current and voltage in a pure inductive circuit?
In a pure inductive circuit, the relationship between current and voltage is such that the current lags behind the voltage by a phase angle of 90 degrees. This means that the current and voltage are out of phase with each other, with the current reaching its peak value after the voltage has reached its peak value.
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 relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
What is the relationship between current and voltage in a simple current?
According to ohms law I=V/R; So current is directly proportional to voltage
What is the relationship between power, current, and voltage in an electrical circuit?
In an electrical circuit, power is the product of current (the flow of electric charge) and voltage (the force that drives the current). The relationship between power, current, and voltage is described by the equation P I x V, where P is power, I is current, and V is voltage. This equation shows that power increases when either current or voltage increases in a circuit.
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.
What is the relationship between current, voltage, and resistance in an electrical circuit?
In an electrical circuit, current is the flow of electric charge, voltage is the force that drives the current, and resistance is the opposition to the flow of current. According to Ohm's Law, the relationship between current (I), voltage (V), and resistance (R) is given by the equation V I R, where voltage equals current multiplied by resistance.
What is the relationship between resistance and current for a given voltage?
Ohm's Law states that the relationship between resistance, current, and voltage is given by the equation V IR, where V is the voltage, I is the current, and R is the resistance. This means that for a given voltage, the current flowing through a circuit is inversely proportional to the resistance - as resistance increases, current decreases, and vice versa.
What is the relationship between current and resistance in a circuit when the voltage is kept constant?
In a circuit with constant voltage, the relationship between current and resistance is inversely proportional. This means that as resistance increases, the current flowing through the circuit decreases, and vice versa.
