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
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.
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 if reactive power enters the system?
Reactive power entering the system will increase the system voltage.
What is the hazard in electricity?
too much power voltage may shock you, and depending on the level of power, the injuries vary.

The name for this is a brown-out.

Reduced voltage levels of AC power that lasts for a period of time is known as a brownout.
What happens if you get a reduced voltage of AC power?
You get something called a brown-out, which plays merry hell with the life expectancy of several types of appliances.

Type your answer here... Which condition refers to a reduced voltage level of AC power that lasts for a period of time?
What is The difference between the voltage going into and coming out of a Town is always how many volts?
A: The difference is none it is called transmission of power. the voltage is very hi 475 kv fed into a sub station Locally at the street level it is reduced to a lower voltage level and that is called distribution from a sub station that has transformers to do that.
When step down transformer is activated what happens?
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
How is voltage reduced when using power tools on site?
If you are working from a generator and many tools are used at the same time, voltage will drop.
What does No-load voltage mean?
A no load voltage means the power level that is giving from the output pins power converter. This is when 0% load is given.
Explian action of zener diode as a regulator?
Zener predicatively will break down at a voltage as manufactured and sustain that voltage as long as the source can provide the current. The limitation is the zener power dissipation for each device. It Regulates by maintaining that breakdown voltage until its current is reduced or its break down voltage is reduced.
If the line voltage is dropped let say to 180V will it not affect my KWH bills to electricity company?
An electrical appliance will only operate at its rated power at its rated voltage. If that rated voltage is, say, 230 V, and the appliance is operated at 180 V, then it will operate at a substantially-reduced power.Since energy is the product of the appliance's power and the time for which it is operated, then the amount of energy used will be reduced and the energy bill will be reduced accordingly.
