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.
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
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.
because current is the ratio of voltage and resistance.
A parallel circuit has the same voltage but different current in each leg and series circuit has the same current but different voltage on each components unless the same value.
The voltage vs current graph represents the relationship between voltage (V) and current (I) in a circuit. It shows how the current flowing through a circuit changes in response to changes in voltage. By analyzing this graph, one can determine the resistance of the circuit, as resistance is equal to the slope of the graph (R V/I). This can help in understanding how voltage and current interact in a circuit and how different components affect the flow of electricity.
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
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.
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
In a capacitor ckt, current will be lead ahead from voltage by an angle 90 degree. Because for a capacitor the relationship between voltage and current is given as v=(jx)i , where v= voltage i= current jx=capacitive reactance
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.
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.
