Verified answer
#6 copper wire has a resistance of 0.3951 ohms per 1000 ft (from wire tables). A 750 ft circuit contains 1500 ft of wire so the resistance is 0.5926 ohms. With 65 amps flowing the voltage drop is 38.5 volts.
The power lost in the cable is 2½ kW.

What are three important characteristics of electric circuit?
Voltage, frequency, current, impedance, and what the circuit is supposed to do are all important.
How does a resistor resist electric current?
A resistor works by limiting the current that goes through it. When current is limited, then voltage across the resistor also changes. We use many forms of resistors in our normal day. Lightbulbs are infact all resistors in one way or another. When the filament in a lightbulb heats up, the resistance increases. When resistance increases, the current is reduced. In the end, the current has been reduced so much that it can no longer carry on heating up the filament. The bulb is then thermally stable and shines for our pleasure.
Why do you always speak about voltage drop and not current?
Voltage is like the pressure in your hose pipe. Current is the flow of charge and equivalent to the rate of flow of the water. Due to resistance to the water in the pipe,the pressure of the water will reduce along the length of the pipe but the quantity of litres flowing in the pipe will not change. So voltage will be maximum at the source of the voltage but as you move along the conductor there is voltage drop due to the resistance of the conductor.However, the current is same at all points along the conductor (the flow of charge is uniform at all points)
What was George Ohm's contribution to the field on electricity?
Georg Simon Ohm 1787 - 1854Georg Simon Ohm discovered how electromotive force works in an electrical circuit, including the relationship that resistance and current play within the circuit.It was Georg Simon Ohm who defined the fundamental laws of current, resistance and voltage in an electrical circuit by using a basic formula:I = E/R (This can also be transposed and rewritten): E = I x R (and also) R = E/IOhm's Law is one of the most important formulas in electrical theory.
In series circuit is currant change with change in resistance?
V=IR where V is voltage, I is current and R is resistance. You want to know what the current will be in a series circuit based on the resistance. You need to know the voltage as well as the resistance, gives you the equation as follows I=V/R So if you have 10 volts and a 1 ohm resistor, the current will be 10 amps. If you increase the resistor to 10 ohms, your current will then be 1 amp. In a parallel circuit, the resistance is equal to the sum of the inverse. For example. If I have two resistors of 2 ohms each in parallel, the equation would be 1/2 + 1/2 = 0.5 + 0.5 = 1 In that particular instance, your current would increase.
What is the voltage source and what is the conductor in a circuit?
The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
What do you nned to make an electric current?
An electrical potential difference (aka. a difference in applied voltage), and a conductor / circuit. Electrons would help too.
How do you work out the current in a circuit?
we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.
What does an electrical circuit need to provide the power?
An electrical circuit needs Voltage-electrical pressure pushing electrons, and Amprege-electron flow through a conductor. P=IxE (Power= Voltage x Amprege.
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
What does a resistor do in a electrical circuit?
Limits current flow and drops voltage.
What is the difference between current and electricity?
The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used. As an example: voltage is a difference in potental and is often considered the amount of pressure pushing an electrical charge or certain number of electrons through a conductor. This electrical charge is called current. Any conductor has resistance to the flow of charge or current. If for example a conductor has a resistance of 2 ohms and a voltage of 12 volts is applied the resulting current flowing in the circuit can be measured to be 6 ampere..the unit for current. Current is therefore, considered the intensity or amount of charge.Electricity then is the movement of this current of charge The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used.

Which charge is voltage carried by in an electrical circuit?
Well, first of all, voltage is not carried. Voltage is the 'pressure' between the ends of a circuit that makes charges want to flow. The charge carriers that actually do the physical flowing are the electrons, with their negative charges. When they flow, we say that there is 'current' in the conductor.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
How do magnets generate electricity?
Magnets generate electricity by moving the magnet along a conductor, such as a wire. This is called induction. When magnetic lines of force sweep across a conductor, the magnetic field induces a voltage in the conductor. Voltage is "electrical pressure" and if a supporting circuit is set up connected to that conductor, current will flow.
What are the three electrical guantities?
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
