Reduced voltage levels of AC power that lasts for a period of time is known as a brownout.
I = E / RCurrent is directly proportional to voltage.If voltage is multiplied by 'X', current will be multiplied by 'X'.If voltage is divided by 'K', current will be divided by 'K'.If voltage is reduced by half, current will be reduced by half.
the power will be reduced to the haflf because P=V2/R so when the resistance doubles the power reduced to the half of itsoriginal value
The low slip test is used to determine the D and Q axis impedance of salient pole machines. The machine terminals are short circuited, each phase voltage and current are measured. Since the terminals are short circuited, machine voltage must be reduced to prevent excessive output currents that would damage the machine.
A: BY adding resistance to one or all branches will reduce the voltage drop across any branch. But also the current will be reduced accordingly
This statement is correct.
by magnetisation of no voltage coil
As the resistance is reduced across the same voltage, the current increases.
Reduced voltage levels of AC power that lasts for a period of time is known as a brownout.
Most 3 Phase 480V Starters are controlled by 120VAC. This is because the coils on the contactors (starters) are 120VAC. Just ensure the voltage matches the coil.

- S2 starters for ignition of low-voltage fluorescent TL lamps and series/single application in high voltage for lower wattages (4 - 22W) - S10 starters for ignition of high voltage fluorescent TL lamps for wide range of wattages (4 - 65W)
A dimmer reduces the voltage to a light so that the current is reduced, which causes the bulb to have a reduced lumen output.
