I=V/R, current = voltage divided by resistance
AnswerOhm's Law states that 'the current flowing through a conductor, at constant temperature, is directly proportional to the potential difference across the conductor'.
Ohm's Law only applies when the ratio of voltage to current is constant over a wide range of voltages. If the ratio changes, then Ohm's Law does not apply.
See OHMS LAW on the internet with a search engine. It will explain everything.
no
Current
Yes, Ohms law is applicable in altering current.
Current density is unrelated to Ohm's Law.
how do you use ohms law express conductance in terms of current and voltage?
Ohms' law says if voltage stays constant resistance controls the current flow. Resistance goes up, current goes down. E/I*R.
Current = voltage/resistance
Ohms law
The mathematical form of Ohms law is I=V divided by R. I is current, V is voltage while R is the resistance.
Ohms law. R = E/I,where R= resistance in ohms, E = voltage in volts, and I = current in amperes.
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
