Loading will cause small voltage fluctuations on the system supplying voltage to your house. Also, the system configuration can change, so you may be supplied from one location today, but switched to a different location tomorrow to allow maintenance to be done without you losing power.

Are high voltage transmission lines 60Hz like the wiring in a house?
Yes, the frequency stays the same. Only the voltage and current change as the voltage is stepped down.
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
How you can reduce voltage of a transformer?
Number of turns in the secondary winding define the voltage. Change the number of turn to change the voltage.
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
What is the voltage of line voltage regularly running through a house?

How can you change dc voltage into ac voltage?
The device to do that is called an inverter.
What is alternator voltage regulation?
change in voltage from no load to full load
What happens to the output in terms of real power of a generator when you change the voltage and frequency say from 220v 50Hz to 110v 60Hz?
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
What is a house or room that is empty called?
A voltage
What is voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.
How do you change the ratio of a current to voltage?
Change the resistance in the circuit
