A wire with some resistance and a voltage applied to it
The amount of current I passing this wire is V/R
What else can I help you with?
How does a current carrying wire differs from a wire through which no current is flowing?
A current-carrying wire has moving electrical charges, creating a magnetic field around it, while a wire with no current has static charges at rest. The current-carrying wire produces a magnetic field perpendicular to the current flow, whereas in a wire with no current, there is no associated magnetic field. Additionally, a current-carrying wire generates heat due to the flow of electrons, while a wire with no current does not.
What is the recommended wire gauge for carrying 80 amps of current?
The recommended wire gauge for carrying 80 amps of current is typically 6 AWG (American Wire Gauge).
What does current carrying wire produce?
A current-carrying wire produces a magnetic field around it. This magnetic field strength is directly proportional to the amount of current flowing through the wire.
When a magnetic field is parallel to a current-carrying wire what is the force on the wire?
When a magnetic field is parallel to a current-carrying wire, there is no force acting on the wire. This is because the magnetic force on a current-carrying wire is perpendicular to both the current and the magnetic field.
Is a wire carrying current charged?
Yes
What is the recommended wire size for a circuit carrying 35 amps of current?
The recommended wire size for a circuit carrying 35 amps of current is typically 8 AWG (American Wire Gauge).
What is the recommended wire size for a circuit carrying 80 amps of current?
The recommended wire size for a circuit carrying 80 amps of current is typically 4 AWG (American Wire Gauge).
Where is the strongest part of magnetic field in current carrying wire?
The strongest part of the magnetic field in a current-carrying wire is near the wire itself, specifically surrounding the wire in a cylindrical pattern. The strength of the magnetic field decreases as you move further away from the wire.
What is the direction of the magnetic field around a current-carrying wire?
The magnetic field around a current-carrying wire is circular and perpendicular to the direction of the current flow.
How do you relate ampere rating with copper wire?
The larger in diameter the wire is, the larger the current carrying capacity the wire has.
Why does a wire carrying electric current become hot?
A wire carrying electric current becomes hot due to the resistance in the wire. As the electric current flows through the wire, the resistance causes some of the electrical energy to be converted into heat energy, which raises the temperature of the wire.
Is a magnetic field line about a current-carrying wire extend radially from the wire true?
No, magnetic field lines around a current-carrying wire form concentric circles perpendicular to the wire. The direction of these circles is determined by the right-hand rule.
