What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
What happens to current in a simple circuit as potential difference is increased?
depends on the simple circuit. please describe it.
When the resistance in a circuit is increased what happens to the current?
The flow of electrons meets an increased impedance to it's flow.
What happens to the current in a circuit when the resistance is increased?
The flow of electrons meets an increased impedance to it's flow.
What happens to the total impedance of a series RC ciRCuit as the frequency is increased?
when the frequency is increased the total impedance of a series RC circuit is decrease.
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
In a closed circuit what does an increase in voltage cause?
an increase in current, hence increased power and increased heat.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
What happens in a circuit if you increase the voltage of the battery driving it?
The power in the circuit will increase.
What happens to a series circuit if a longer wire is used?
Resistance is increased so the light will be dimmer.
What happens to a circuit if the resistances is increased?
The voltage drop across each resistance will go up, and the current through the circuit will go down.
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.
