How many degrees are the current and voltage out of phase in a pure capacitive circuit?

In a pure (ideal) capacitive circuit, current leads voltage by 90 degrees.


In a pure inductance circuit the current lags the voltage by what degree?

90 degrees


Why the voltage drop across inductance and voltage drop across capacitance is greater than source voltage in series resonance circuit?

The reason for the total voltage drops across the capacitance and inductance IN AN AC CIRCUIT has to do with the different phase angles of the voltages.First, current is the same value and same phase angle everywhere in a series circuit. But, voltage across a capacitor lags current by 90 degrees (capacitor current leads voltage). Next, voltage across a pure inductance leads current by 90 degrees (inductor current lags voltage).The rule that all voltages in a series circuit have to add to the supply voltage still applies, but in this case, the voltage drops are added VECTORALLY, not arithmetically. If you were to graph this addition, you would show any resistance voltage in phase with the current, the capacitor voltage at -90 degrees to the current and the inductor voltage at +90 degrees to the current, for a phase difference between them of 180 degrees, cancelling each other out.In a series resonant circuit, the impedances of the capacitor and inductor cancel each other. The only impedance to the flow of current is any resistance in the circuit. Since real-life inductors always have some resistance, at least there is always some resistance in a series resonant circuit.


If voltage changes in a ac circuit what happens to current?

Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.


If voltage is increased in a circuit what happens to current series and parallel respectively?

In this case current flows from a high voltage to a lower voltage in a circuit.

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.


How does the potential difference across the electric circuit affect current?

In a very simple way. As long as nothing changes in the circuit, the current that flows from the power supply or battery into the circuit is directly proportional to the voltage of the supply. -- If you double the voltage across the ends of the circuit, the current will double. -- If you turn the voltage up to 3.4027 times its original value, the current will increase to 3.4027 times its original value. -- If you decrease the voltage by 81.7 percent, the current will decrease by 81.7 percent.


The phase angle between voltage and current in an a c circuit through a pure capacitance is?

90 degrees. In an AC circuit with a pure capacitance, the current leads the voltage by 90 degrees. This is because the current in a capacitor is proportional to the rate of change of voltage across it, leading to this phase relationship.

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.


How does changing the voltage in a circuit affect the current in the circuit?

Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
