The answer is 1. We assume you are converting between volt/ohm and ampere. You can view more details on each measurement unit: volt/ohm or ampere The SI base unit for electric current is the ampere. 1 ampere is equal to 1 volt/ohm, or 1 ampere.

For example if the power is 100 watts and the voltage is 50 volts, the current is 100 / 50, or 2 amps. Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current.

The relationship between resistance and the area of the cross section of a wire is inversely proportional . When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result.

The power is inversely proportional the resistance based on the equation P = (V^2)*R. The power is independent of the resistance and is constant for a fixed resistance regardless of voltage and current changes.

The relationship between the voltage (V), resistance (R), and current (I) is V=IR; this is known as Ohm's law. An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region.

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Current is equal to the voltage divided by resistance of the circuit, therefore, the greater the voltage for the same resistance creates more current, therefore more energy, some of which is released as heat which will raise the temperature. There is NO relationship between temperature, voltage and current.

The relationship between Potential Difference, Resistance, and Current is given by Ohm's Law, which states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.

Use these values in Ohm's Law. If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I.

The relationship between current and voltage is direct - as voltage increases, current increases. The relationship between current and resistance is inverse. As resistance increases, current decreases (for a fixed voltage). The light bulb filament changes temperature and therefore changes resistance.

You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +... If one of the parallel paths is broken, current will continue to flow in all the other paths.

Ohm's Law and Resistance. Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.

Current is directly proportional to electric potential difference and inversely proportional to resistance.

This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. But, if we increase the resistance, then the current will decrease.

V = IR (voltage equals current times resistance). So if you have a voltage applied across a circuit of constant resistance, the current will be proportional to the voltage. ... Voltage is a measure of the energy per unit charge; amps are a measure of how much charge is flowing.

The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
