What else can I help you with?
Why does the current immediately increase in current after reaching a certain voltage rather than a gradual current increase?
It depends on the nature of the circuit. In a purely-resistive circuit, the current would rise immediately because resistance merely limits its value, it doesn't oppose any change in current. But in a resistive-inductive circuit, for example, the inductive component opposes any change in current, so the current will rise more gradually.
When a series circuit containing resistance and inductive reactance is connected to a ac supply the current will?
The load current will lag the supply voltage by an angle called a 'phase angle', determined by the values of resistance and inductive reactance. The magnitude of the load current will be determined by the impedance of the circuit, which is the vector sum of the resistance and inductive reactance.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
In RC circuits the voltage leads the current?
Inductive. Used to remember this by "Eli" the "ice" man. "(e) Voltage (l) (Inductive circuit) (i) current", the ,"(i) Current (c) (capacitive circuit) (e) voltage, man.
Why is capacitive voltage higher than inductive voltage in an R-L-C circuit?
It isn't necessarily so. The capacitive voltage is the product of the current and capacitive reactance, while the inductive voltage is the product of the current and the inductive reactance. So it depends whether the capacitive reactance is greater or smaller than the inductive reactance!
A circuit with a lagging current means the circuit is?
Inductive. Voltage (E) leads current (I) in an inductive (L) circuit and current (I) leads voltage (E) in a capacitive (C) circuit. (ELI the ICEman)

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 phase between voltage and current in a pure inductive circuit?
The phase angle between voltage and current in a purely inductive circuit, under ideal circumstances where there is no resistance at all, is 90 degrees.
What is the Opposition to current flow in a inductive ac circuit?
Back EMF.
Why a spark is produced in the switch of a fan when it is switched off?
when inductive load is switched off then current decreases as a result emf induced in the inductor or as whole of the circuit. There is air between switch and circuit wire. Emf tends to jump from higher pd to lower pd so air become ionised and spark is prouced

Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
What factors affect the inductive reactance of a coil in a A C circuit?
Current Flow I believe.

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.
