What else can I help you with?
Why does higher resistance have a larger voltage drop across it?
In a d.c. circuit, voltage drop is the product of resistance and current through that resistance.
What is electricity current potential difference and resistance?
Voltage is the electrical pressure in a circuitAmperes (amps) are the measure of electrical current in a circuitOhms are the measurements of resistance in a circuitCurrent is essentially how fast electrons are moving in a circuitResistance is what impedes the electrical current, and can be found in the wire or various loads in a circuitHope this helps!
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
What determines the amount of electric current flow through a circuit?
voltage and resistance v=ir v=voltage i=current r=resistance in physics right now
What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
Does resistance use amps or voltage?
Resistance doesn't "use" either. Resistance is the division of voltage by current. It can be though of as a measure of how hard it is to push electrons through a substance.
What is the electrical pressure that causes electrons to flow?
Voltage, measured in volts, is the electrical pressure that causes electrons to flow in a circuit. Voltage is what pushes electrons through a conductor, such as a wire, and is necessary for the flow of electrical current.
What can cause the flow of electricity to slow down?
No, electricity will not slow down with increased resistance. The number of electrons moving through a conductor will decrease with increased resistance. Also there will be a drop in the voltage (electrical pressure) with increased resistance. Look up Ohms Law for formulas relating to voltage, resistance, and amplitude. E=I*R. E=voltage (pressure), I=the current (flow of electrons) R=the amount of resistance or the strength of the opposing flow of electrons. The speed of an electron through a conduvtor will always remain the same.
What is the pressure that pushes current measured in?
Current is pushed by voltage, which is the electrical pressure that drives the flow of electrons through a circuit. The relationship between current and voltage is described by Ohm's Law, which states that current (I) is equal to the voltage (V) divided by the resistance (R), represented by the formula I = V / R.
Would it be true to say that current causes voltage?
Volts = Current x Resistance. The voltage is where the potential resides for the amount of current flowing through a resistance. Think about the voltage as a potential source of electrons that then flow through a circuit depending on the Load, or resistance in this example.
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
What force keep current flowing?
Voltage is the pressure that moves the electrons (current) through a circuit.
Is voltage the flow of electrons through a wire or a conductor?
The flow of electrons through a conductor is called electric current.The voltage is the 'pressure' or difference in electric potential between theends of the wire, that encourages each electron to try to move closer toone end and farther away from the other end.
Does ohms law state that current equals flow of electrons through a conductor?
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. So, it doesn't specifically equate current to the flow of electrons, but it does explain how current, voltage, and resistance are related in a circuit.
''Ohm's law is the tendency for material to oppose the flow of electrons''is this true?
No, that statement is not accurate. Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, given a constant temperature. It describes the relationship between current, voltage, and resistance in a circuit.
What is resistance What is an electron Can electrons flow through all materials What materials are good for an electron to go through Is resistance inside of an electron?
Electrical resistance is just that: obstruction to the flow of electrons, which are (generally speaking) electric current. Electrons are what orbit the nucleus of an atom. You can force them out of their various orbital shells by using the proper voltage. Many non-conductive materials are not suitable for electron flow because they have a high resistance, e.g. glass. But if you send enough voltage through materials with high resistance the electrons will arc through the air across the top of the material. Note: You can, with a high enough voltage applied in a particular manner, cause the material itself to "fail" and conduct electricity. The high voltage will destroy the material when it ionizes the atoms within it. We can generate voltages high enough to punch through anything. Almost anything metallic is a good material for an electron to go through. In general, metals are good conductors of electricity. They have a low resistance.
What pushes electricity through the wire?
Electricity is pushed through a wire by the electric field generated by a difference in electrical potential (voltage) between two points. This potential difference creates a force that drives the flow of electric charge (electrons) through the wire.
