What is a current-carrying wire?
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
Why do current carrying conductors kept in a magnetic field experiences a force on what factor does this depends?
Magnetic fields currently flows through a conductor is determined by multiplying the number of turns of wire by the current flow. This is what causes electricity.
Moving a wire through a magnetic field does not create a current flow in a wire?
Not true - Moving a wire through a magnetic field doescreate a current flow in a wire.false
How much current at 240 volts passes through a wire with a resistance of 100 ohms?
current = voltage/resistanceAssuming the 240 volts is across the 100 ohm wire, 2.4 amperespower = current * voltageResulting in the wire dissipating 576 watts... One hot wire!
Does a transformer increase amps?
The primary current is determined by the secondary current, not the other way around. For example, a step up transformer will step up the primary voltage in proportion to the turns ratio of the transformer. Any secondary current is then determined by the secondary voltage and the load, NOT by the primary current. The primary current is then determined by the secondary current in proportion to the reciprocal of the turns ratio.
What is the magnetic field around a wire when the current running in the wire is in reverse direction?
The magnetic field around a wire is determined by the direction of the current flow. If the current running in the wire is in the reverse direction, the magnetic field around the wire will also be reversed. The direction of the magnetic field is determined by the right-hand rule, where if you wrap your right hand around the wire with your thumb pointing in the direction of the current, your fingers will point in the direction of the magnetic field.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
When current passes through a wire?
When current passes through a wire, it creates a magnetic field around the wire. The direction of the magnetic field is determined by the direction of the current flow. This principle is the basis for electromagnets and various applications in electrical devices.
What is the magnetic field due to the current carrying wire in figure 21-4b?
The magnetic field due to the current carrying wire in figure 21-4b is determined by the right-hand rule and is perpendicular to both the current direction and 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.
What is the wire size for 208 volt?
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
What does a wire with current going through it produced around it?
A wire with current flowing through it produces a magnetic field around it according to Ampere's law. The direction of this magnetic field is determined by the right-hand rule. The strength of the magnetic field is directly proportional to the current in the wire and inversely proportional to the distance from the wire.
How much current should the solenoid carry if it has 1000 turns of wire?
The current flowing through a solenoid with 1000 turns of wire depends on the resistance of the wire and the voltage applied across the solenoid. Using Ohm's Law (I = V/R), the current would be determined by both the voltage and the total resistance of the wire in the solenoid circuit.
When a wire with a current is placed in a magnetic field....?
...a force is exerted on the wire perpendicular to both the current direction and the magnetic field direction. This is known as the magnetic force. The direction of the force is determined by the right-hand rule.
What is magnetic field produced by a current flowing through a wire?
A current flowing through a wire produces a magnetic field around the wire. The direction of the magnetic field is determined by the right-hand rule, where if you point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines. The strength of the magnetic field is directly proportional to the current flowing through the wire.
How is a coil of wire that carries a current similar to a bar magnet?
A coil of wire carrying a current generates a magnetic field, similar to a bar magnet. Both have north and south poles, with the direction of the magnetic field lines determined by the direction of the current flow in the wire or the orientation of the bar magnet's poles.
How does the direction of magnetic field affect the movement of wire?
The direction of the magnetic field affects the direction of the force on a wire carrying current. When the magnetic field is perpendicular to the current in the wire, a force is exerted on the wire causing it to move in a particular direction. The direction of the force is determined by the right-hand rule.
