Resistance is a measure of how well current flows through the material. As such, voltage divided by current in amps results in resistance

The resistance of a wire is the length divided by the cross-section area and the conductivity of the material. So for small resistance you need a wire with short length, large cross-section area (diameter) and a material with high conductivity like copper.

Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.

Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance

By Ohm's Law, resistance is voltage divided by current.

Ohm's Law Voltage = Current x Resistance Current = Voltage divided by Resistance Resistance = Voltage divided by Current

Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.

Ohm's law relates voltage, current, and resistance. Voltage is current times resistance Current is voltage divided by resistance Resistance is voltage divided by current

Ohm's Law: Current = Voltage divided by Resistance, so, if you increase resistance, then current decreases.

Ohm's Law Voltage = Current x Resistance

No. Voltage divided by resistance is equal to current.

Because the current is zero and the resistance is voltage divided by current.

Power is inversely proportional to resistance. Ohm's law: Current is voltage divided by resistance Power law: Power is voltage times current, therefore power is voltage squared divided by resistance.

resistance

If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.

When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.

This question makes no sense. You are asking for resistance and then saying the resistance is 10 us. "US" is not a measure of resistance. The measure is called Ohms. Ohm's Law states that Voltage = Current x Resistance Hence Resistance = Volts divided by Amps.

Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.

That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.

False. Current is voltage divided by resistance.

Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.

Ohm's Law Resistance = Voltage divided by Current R = V/ I

Basic: The larger the diameter the less resistance.Deep:R = p (L / A)The resistance is proportional to the length of the wire divided by its cross-sectional area. p is the resistivity of the material in question and varies greatly. Since area (assuming a circular wire) is A = pi * r2 the larger the diameter of the wire the lower its resistance will be.AnswerResistance is inversely proportional to the square of the diameter. So, if you double the diameter, you will quarter the resistance. If you halve the diameter, you will quadruple the resistance.

I need to know the resistance to figure out the current Voltage = Current X Resistance Your answer will be: 480V divided by your total resistance = Amps

Given voltage and resistance, power is voltage squared divided by resistance. Ohm's law: Current is voltage divided by resistance Power law: Power is voltage times current, or voltage squared divided by resistance
