In a pure inductance circuit the current lags the voltage by what degree?
90 degrees
What is a purely resistive circuit?
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
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.
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.

Which of the following condition exist in a circuit of pure resistance?
in a circuit of pure Resistance (r), IE. voltage source (12 v DC battery) and pure resistance (a light bulb). the voltage (v) and current (i) will be in phase. by adding capacitors and/or inductors to the circuit V and I will be pulled out of phase.
What is a pure capacitor?
A pure capacitor is an idealized version of a capacitor that has only capacitive reactance and no resistance or inductance. It stores and releases electrical energy in the form of an electric field. Pure capacitors are often used in electronic circuits for filtering, smoothing, timing, and energy storage purposes.
Does copper exist in its pure form?
Yes it is available in its pure form
Does pure water exist?
yes

How can copper and iron exist in there uncombined form?
Copper and iron can exist in their uncombined form in nature as pure elements because they are relatively stable metals. This means that under certain conditions, they can exist in a metallic state without needing to form compounds with other elements. In the case of copper, it is often found in its pure form as nuggets or veins in the Earth's crust, while iron can also be found in its pure state in meteorites or certain iron-rich minerals.
Is a homogeneous mixture a pure mixture?
The term pure mixture doesn't exist; the components can be more or less pure.
Does manganese exist in its pure form?
No - not naturally, it usually exist with other elements. To achieve a pure form, MnO2 needs to be heated with carbon to remove the oxygen.
Does 100 percent pure aluminum exist?
Yes.
