Name a device that helps to maintain a potential difference across a conductor?
volt meter is the device that helps to maintain a potential difference across a conductor
What happen is the potential difference across is double?
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.
Q 1 Name a device that helps to maintain the potential difference across a conductor?
voltmeter
Correct statement of Ohm's Law?
The current flowing through a conductor is directly proportional to the potential difference across that conductor, providing conditions such as temperature doesn't change.
The ratio of the potential difference across a metallic conductor to the current in the conductor is known as?
That is the resistance, measured in ohms.
Which would cause most of the free electrons to move in a conductor to move in the same direction?
In the theory of electricity, you must have a current for electrons to all move in one direction.
How come birds on electric wires dont get electrocuted?
For an electric current to pass through the bird's body, there must be a potential difference (voltage) across its legs. But its legs are connected to a very good conductor which means that the bird's legs must be at the same potential -no potential difference, no shock!
A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?
The potential difference across the secondary coil will be 147.42 Volts
How is electrical current produced?
A potential difference (volts) is set up between the two ends of a conductor. If there are any electrons available to move, then their negative electric charges persuade them to move away from the more negative potential and toward the more positive potential, resulting in current.
What is the potential difference across a single 4 Ohm resistor if the source voltage is 230v?
the potential difference across the single 4ohm resistor is 230volts.
How do you generate electricity from fast moving electrins in a metal rod?
By applying a potential difference across the ends of the conductor so that all electrons move topwards one terminal only.
What equation states ohm's law?
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.eq: V=IR where V= potential differenceR= resistanceI=current
