What would be the effect on the voltage level at the load if the distance between the electrical supply point and the load appliance is increased?

As the resistance in the wire increases due to the longer length the voltage drop across the wire resistance increases. This leaves less voltage across the load. To overcome this voltage drop usually a larger size wire which has less resistance is used. A safe nominal figure for voltage drop is to keep it at 3% of the line voltage.

Power lines and electronic equipment: 150m
When is earthing required?
As it's a safety factor, earthing is essential and mandatory. It's an electrical connection between the exposed metallic parts of an electrical appliance or installation and the earth, regarded to have zero potential. Proper earthing provides an alternative and easy path for leakage or faulty current to flow. It ensures that any exposed conductive part of the appliance does not reach a dangerous level of potential or voltage that endangers the user's life. A proper earthing system should have least electrical resistance, good corrosion resistance and ability of dissipating high faulty current.
Why do the two wires running from an energy source to an appliance have insulation between them?
If they didn't, and the wires touched, all energy would be spent on a short-circuit at the point of contact rather than on powering the appliance. Also, if a bare wire touches the appliance, that itself would start to carry an electric charge, giving anybody who touched the appliance a nasty and dangerous shock.
What is difference between electrical angle and mechanical angle?
Electrical angle is half of mechanical angle in unipolar electrical machines. In multipolar electrical machines, the relationship between the mechanical angle and electrical angle is Electrical angle = (P/2) x Mechanical angle where: P = Number of poles.
What is the difference between core and cord?
A cord is often the same thing as a cable or a wire, as in power cord - the cable between an electrical appliance and the wall socket. A core is something that inside, either physically in the center (like an apple core), or central in terms of importance, like the core of the emergency services(firefighters, ambulance etc) is a willingness to help people.
What is the difference between an electrical appliance and a machine?
The machine can work by itself, but and electrical appliance needs somebody to manipulate it...like an iron for example.
When the distance between two charges is increased by a factor of six what is the electrical force between the charges?
The electrical force between two charges is inversely proportional tothe square of the distance between them.If the distance increases by a factor of six, the new force compares tothe old force by a factor of1/(62) = 1/36 = 7.72% (rounded)

Why do birds roosting on a electrical wire have an equal distance between them?
They have equal distance between them to keep balance.
When the distance between two charges is three time far apart electrical force between the charge is?
Electrical forces are inversely proportional to the square of the distance separating the charges.
What happens to the distance between the spinous processes during flexion of the spine?
During flexion, the distance between the spinous processes is increased.

What happens to the gravitational force between two objectes if the distance between them is increased?
the gravitational force between them decreases.
What happens to the gravity as the distance between the objects is increased?
The size of the force decreases. It is inversely proportional to the square of the distance.
Why does capacitance increase when the distance between the plates of a capacitor is increased?
you have it reversed. capacitance increases with decrease in distance of plates.
What happens to the distance interference fringes if the separation between the slits is increased?
decreases
What is the maximum distance between two electrical manholes?
