What are the factors affecting ohms law?

Answer 1

Ohm's law states that the resistance of current between two points is proportional to the potential difference.

R = V / I

R is resistance in Ohm's, V is potential in Voltage and I is current in Amperes.

Answer 2

Ohm's law has the factors, Voltage, current and Resistance.

Voltage in Volts

Current in Amperes

and Resistance in Ohm's.

The formula is : V=I x R

and can be transposed to find one of the values as long as the other two are known.

In the basic formula. The voltage across a resistor = the current (in Amps) flowing through it, multiplied by the resistance (in Ohms).

Answer 3

Ohm's Law is not a 'universal law', and only applies to linear or ohmic materials.

If the ratio of voltage to current is constant for variations in voltage, then Ohm's Law applies.

If the ratio of voltage to current varies for variations in voltage, then Ohm's Law does not apply.
