Voltage across a conductor creates an electric field that causes free electrons to move, resulting in an electric current. This potential difference drives the flow of charge carriers, allowing electrical energy to be transmitted through the conductor. The amount of current that flows is directly proportional to the voltage applied, as described by Ohm's Law. In essence, voltage is the force that pushes electrons through a circuit.
What else can I help you with?
When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
Why is the voltage across a battery in a parallel circuit equal to the voltage across each bulb?
The voltage across a battery in a parallel circuit is equal to the voltage across each bulb because Kirchoff's Voltage Law (KVL) states that the signed sum of the voltages going around a series circuit adds up to zero. Each section of the parallel circuit, i.e. the battery and one bulb, constitutes a series circuit. By KVL, the voltage across the battery must be equal and opposite to the voltage across the bulb. Another way of thinking about this is to consider that the conductors joining the battery and bulbs effectively have zero ohms resistance. By Ohm's law, this means the voltage across the conductor is zero, which means the voltage across the bulb must be equal to the voltage across the battery and, of course, the same applies for all of the bulbs.
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the what?
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the length and the speed of the conductor.
Does voltage flow through a circuit or is voltage establish across a circuit?
voltage does not flow, current flowsAnswer'Voltage' is another word for 'potential difference' -you can think of it as being the equivalent of the difference in pressure across, say, the input and output ports of a central heating radiator which is responsible for pushing water to flow through that radiator. So 'voltage' exists across two points in a circuit, causing current to flow through the conductor between those two points.
What is the relationship between voltage and MA?
The "current" through any conductor is voltage across the conductor/conductor's resistance .The current is measured in "Amperes" (amps)."MA" stands for "Milliamps". There are 1,000 of those in one whole ampere.So, the current through a conductor is1,000 times the voltage across the conductor/conductor's resistance . . . in MA
How can the current in a conductor be increased?
The current in a conductor can be increased by either increasing the voltage applied across the conductor or decreasing the resistance of the conductor.
When does current flow through a conductor?
When a voltage is applied across it.
What is the process called in which a conductor cuts across a magnetic field and produces a voltage?
We call it induction when we pass a conductor through a magnetic field to produce voltage.
When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
What is hall effect hall voltage?
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
Does a light bulb obeys ohms law?
Yes, a light bulb obeys Ohm's law since its resistance is constant as long as the voltage across it is constant. Ohm's law states that the current through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
The voltage drop in each resistance is?
V=IR by ohms law. Voltage across the resistor is the product of current flowing and resistance of the conductor at constant temperature.
The output voltage between phases of ac 3 phase supply is 240V?
No, this voltage appears ACROSS individual phases, or BETWEEN a line conductor and the neutral
What is non ohmic material?
A 'non-ohmic' conductor is one that does not obey Ohm's Law -i.e. the ratio of voltage to current is not constant when the voltage across it varies.
How do magnets generate electricity?
Magnets generate electricity by moving the magnet along a conductor, such as a wire. This is called induction. When magnetic lines of force sweep across a conductor, the magnetic field induces a voltage in the conductor. Voltage is "electrical pressure" and if a supporting circuit is set up connected to that conductor, current will flow.
What regulates amperage in a conductor?
Amperage in a conductor is primarily regulated by the voltage across the conductor and the resistance of the conductor itself, as described by Ohm's Law (I = V/R). When voltage increases, amperage increases, provided the resistance remains constant. Conversely, higher resistance results in lower amperage for a given voltage. Additionally, factors such as temperature and the material properties of the conductor can also influence resistance and thus affect amperage.
