A: Perfect example is a zener. As input voltage increases the current at the knee increases almost linearly at the zener voltage. If the inputs varies up or down then the current will vary up or down at the preset voltage making a zener a voltage regulator because of this feature

What happens when a bypass capacitor is shorted?
The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.
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 voltage error circuit and current error circuit?
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
What is the voltage gain and current gain for a voltage follower?
In a voltage follower, voltage gain is 1, with an offset of VB-E, and current gain is hFe, limited, of course, by the available current in the supply and by the rating of the transistor.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance

What happens to current flow in a capacitive circuit in comparison to voltage?
The current leads the voltage by 90degree....
What is operating points?
the voltage at which voltage collector emmiter & collector current becomes zero
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.
In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.

What happens to the electric current in a wire when voltage is increaced?
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
What happens to zener current after the breakdown voltage is reached?
After breakdown voltage is reached in a zener diode the current increases drastically.
What is the voltage gain and current gain for a voltage follower?
In a voltage follower, voltage gain is 1, with an offset of VB-E, and current gain is hFe, limited, of course, by the available current in the supply and by the rating of the transistor.

It is halved. coz voltage=current * resistance
What happens to voltage when a reactor limits current?
the currents path blocks & normal voltage will flow
