How do you calulate the voltagedrop in an electrical circuit of the current draw was 65 amps and the circuit was 750 feet long with No. 6 TW conduct?

Look up in wire tables the resistance per ft for #6 wire (in ohms). Multiply by the total length of wire, 1500 ft because the current has to go through both wires. The answer is the total resistance of the cable. Then multiply by the current, 65 amps, and that's the volt-drop.
In this example the total resistance is 0.59 ohms and the volt drop is 38.5 v. This cable can carry 65 amps but at this length the volt drop may be excessive and that is a reason for using a thicker conductor.

Why you have to make sure of your hands are dry when i am using electrical equipment?
Water on hands could conduct electricity into your body if there is short circuit in the electrical device.
What type of circuit cannot conduct an electric current?
An open circuit.
What is necessary to conduct electricity in a closed open circuit?
yes
What has the ability inability to conduct an electrical current is called?
Conductivity
Why does a pineapple conduct electricity?
Biological materials, such as this one, will usually conduct electricity due to ions in the liquid. Since an ion has an electrical charge, and is relatively free to move around, it can conduct an electrical current.
Which substance can be used to conduct electrical in a circuit?
Metal
Why is an electrical circuit made of materials that are conductor?
"Electrical circuit". "Electrical" meaning "electricity". "Circuit" meaning "around from the start back to the starting place". If any of the materials in that circuit path are not conductors, there is no circuit. The electricity only goes that far and stops. So all materials in the circuit must be able to conduct electricity.
Why you have to make sure of your hands are dry when i am using electrical equipment?
Water on hands could conduct electricity into your body if there is short circuit in the electrical device.
How does a resistor slow down the flow of change in a circuit?
It is made of a semiconductor that doesn't conduct electricity as well as the rest of the circuit. It dissiapates some of the electrical energy as the current flows through it.
why water electrical conductors?
Pure water by itself is not much of an electrical conductor. You can increase the ability of water to conduct electricity by adding a substance such as a salt that dissolves in water, separating into positive and negative ions. The ions in the water are able to conduct/transfer electrons maintaining an electrical circuit through the water.
If you remove one bulb from a string of lights all the remaining lights will go out. are the lights in a series circuit or parallel circuit Explain?
Removing any bulb breaks the continuity of a series circuit, stopping the flow of electrical current. Removing a bulb in a parallel circuit does not interrupt the current flow, so the remaining lights continue to conduct electrical current.
Will an electrical circuit with a battery be completed by two copper electrodes in an empty beaker when the beaker is filled with distilled water?
No, distiled water will not conduct electricity.
What is the use of conductance?
When referring to electrical conductance, it is used in the application of electricity to equipment. Electrical conductance measures the equipment's ability to conduct electrical charge. A practical application would be to decrease the resistance in an electrical circuit so that the conductance is higher and electricity flows more smoothly.
What type of circuit cannot conduct an electric current?
An open circuit.
Materials that do not conduct electrical charges at all are called insulators?
No material exists that doesn't conduct electrical charges at all. We call materials that conduct electrical charges poorly insulators; a material that didn't conduct electricity at all would be a perfect insulator.
What is an electrical insulator an conductor?
The substances that do not conduct electricity are called electrical insulators while those which conduct electricity are called conductors.
What is the best conduct to use in a circuit?
metal
