Which conditions refers to a reduced voltage levels of AC power that lasts for a period of time?
Reduced voltage levels of AC power that lasts for a period of time is known as a brownout.
What happens to power when current and voltage is reduce to one half?
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.
What happens to the power if the resistance of a circuit doubles and voltage remains the same?
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
Why in slip test the machine voltage reduced?
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.
What can be used to reduce the amount of voltage drop across the branches of a parallel circuit to be less than source voltage?
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
