For a formula of resistance. Is it correct to divide the current by the voltage rather than the other way around?

Ohm's law says V=IR, where V is voltage, I is current and R is resistance. To get resistance, divide both sides by I:
V/I = R. If you check the units, you'll see that they work out this way, but would not work out correctly if you tried I/V.
(but remember, this only applies to systems which obey ohm's law, which is usually not quite true in real systems, but is generally true in textbook problems)

AnswerA tungsen lamp doesn't obey Ohm's Law , because the ratio of voltage to current varies as the applied voltage varies. However, the ratio of voltage to current will tell you what the resistance of the lamp happens to be for any particular voltage.

What is the dimensional formula for current?
One way to calculate current is using ohms law; current equals voltage divided by resistance or: I=V/R Where I is current, V is voltage and R is resistance.
How are voltage resistance and current related?
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. Stated mathematically: I = E/R where I = current in amperes, abbreviated to A E = voltage in volts, abbreviated to V R = resistance in ohms, usually signified by the Greek omega Ω
How do you work out the current in a circuit?
we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
How do you test leakage on equipment?
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.
What is the Mathematical formula for OHMS law?
Current = voltage/resistance
What is the formula for electrical resistance?
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)

What is an example of mass resistance?
An example of mass and resistance is voltage, we know that the following is the formula for calculating voltage: V = IR where R is the resistance and I is the current.
What is the formula of calculating effective current if resistor and voltage is given?
I = E/R or Current = Voltage/Resistance (Ohm's Law)
How are voltage resistance and current related?

If the resistance of an electric current is 12 ohms and the voltage in the current is 60 V the current flowing through the circuit is?
..using the formula Voltage(V)=Current(I) * Resistance(R) .. we can get the result ...current will be 5 Ampere
What is the mathematical formula for voltage current and resistance can be mathematically called?
Ohm's Law
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
