Ohm's Law:
V = IR
Solving for current:
I = V/R
To affect the current, you can either change the voltage (more voltage --> more current), or the resistance (more resistance --> less current).
Electric current produces magnetic fields around the conductor through which it flows, according to Ampère's law. Additionally, electric current also generates heat due to the resistance of the material through which it passes.
Yes, electric current does create magnetic fields
Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.
In the field of volt physics, voltage and electric current are directly related. Voltage is the force that pushes electric current through a circuit. The higher the voltage, the greater the potential for electric current to flow. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I V/R.
A changing magnetic field induces an electric current in a conductor, according to Faraday's law of electromagnetic induction. This is because the changing magnetic field creates an electric field that causes charges to move within the conductor, generating an electric current.
ohm's law state that in an electric current it is propotional to current
Ohms law
Electric current produces magnetic fields around the conductor through which it flows, according to Ampère's law. Additionally, electric current also generates heat due to the resistance of the material through which it passes.
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.
Ohm's law is the basic answer. Voltage = Current * Resistance is ohms law. In order to find current divide voltage by Resistance V/R=I where I is current.
Yes, electric current does create magnetic fields
An electric current produces a magnetic field around wires where the current exists.
Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.
Generally, a Girl Guide or Girl Scout organization will change their Law to make it more current to the times. Sometimes it is changed to make it easier to remember. When ever the Law is changed, it must follow the guidelines set by the World Association of Girl Guides and Girl Scouts (WAGGGS). The Girl Scout Law for Girl Scouts of the USA was changed in 1996 to make it more current and easier to remember and say.

A changing magnetic field induces an electric current in a conductor, according to Faraday's law of electromagnetic induction. This is because the changing magnetic field creates an electric field that causes charges to move within the conductor, generating an electric current.
In that case, the current will also be doubled. This follows from Ohm's Law (current = voltage / resitance)
