Electric current does not drop. Electric voltage, however, drops across a wire because the wire has non-zero resistance. (Do not confuse electric current with electric voltage - they are not the same.)
The reason current does not drop is that, in a series circuit, according to Kirchoff's current law, the current at every point in a series circuit is the same.
What else can I help you with?
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!
What property of a wire increases when it is made thinner?
It's resistance to electric current increases.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
What device works by rotating a wire coil within a magnetic field to produce electric current?
inductor
Electric current in a copper wire is normally composed of what?
Electric current in a copper wire is composed of moving electrons. When a voltage is applied across the wire, the free electrons in the copper atoms move in response to the electric field, creating the flow of current.
Does copper wire carry electric current?
Yes, copper wire is an excellent conductor of electric current due to its high electrical conductivity properties. When a voltage is applied across the wire, it allows the flow of electrons, resulting in the transmission of electric current through the wire.
What happens to the needle of a compass as a wire carrying electric current is placed across it?
The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.
How is current carried through a wire?
Current is carried through a wire by the flow of electrons. When a voltage is applied across the wire, electrons move from the negative terminal to the positive terminal, creating an electric current. The movement of electrons creates an electric field along the wire, allowing for the flow of current.
What is the process by which electric current is generated by placing a wire in a field?
electromagnetic induction
What is the relationship between electric potential and a wire in an electrical circuit?
The electric potential in a wire in an electrical circuit is the amount of electric potential energy per unit charge. As the wire carries current, the electric potential decreases along the wire due to the resistance of the wire. This relationship is described by Ohm's Law, which states that the electric potential difference across a wire is directly proportional to the current flowing through it and inversely proportional to the resistance of the wire.
What would induce a greater electric current in a wire?
A greater electric current in a wire can be induced by increasing the voltage applied across the wire or decreasing the resistance of the wire. Both factors contribute to Ohm's Law (V=IR), where V is voltage, I is current, and R is resistance. Increasing the voltage or decreasing the resistance will lead to a higher current flowing through the wire.
Device that produces current by moving a magnetic field across a wire?
This device is called a generator. When a magnetic field is moved across a wire, it induces a flow of electrons in the wire, creating an electric current. Generators are commonly used to convert mechanical energy into electrical energy in power plants and electric generators.
How does an electric generator generate an electric current The generator?
The rotor turns (rotates) causing magnetic fields to move across a coil of wire. This induces an electrical current in the wires of the coil.
What causes charge to flow in a conducting wire?
The flow of charge in a conducting wire is caused by the presence of an electric field. When a potential difference (voltage) is applied across the wire, it creates an electric field that exerts a force on the free electrons in the wire, causing them to move and create an electric current.
A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
How would you find out the length of the wire effects the voltage drop across the wire when the current passing is kept constant?
A: There are tables that qualify IR drops for wire lenght. All wire do offer resistance to current this current will cause directly a volatge drop according to the wire resistance so it can be measured to find the IR drop
