Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
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.
By Ohm's Law.... Voltage equals Current times Resistance (V=I*R) So if given the voltage and resistance of a system and applying algebra I=V/R .
The equation you are looking for is R = E/I.

Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
to fine I (current) when you have R (resistance) and V (voltage) you use the formula: I = V / R
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
To calculate an object's resistance, you would need to know the material's resistivity, its length, cross-sectional area, and temperature (if it's a variable). Using these values, you can apply the formula R = Ο * (L/A) to calculate the resistance, where R is resistance, Ο is resistivity, L is length, and A is cross-sectional area.
V=IR so, R=V/I or resistance = Voltage / Amps Therefore, the resistance (R) = 9 volts / 3 Amps answer: 3 Ohms
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
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.
The unit of resistance is the Ohm, and by applying a small voltage to your wire, and measuring the resultant current, you may calculate the resistance.From the formula I = E/R, where R = resistance in Ohms, E is the voltage in volts, and I is the current in amperes.
By Ohm's Law.... Voltage equals Current times Resistance (V=I*R) So if given the voltage and resistance of a system and applying algebra I=V/R .
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
Current flow can be calculated using Ohm's Law, which states that current (I) is equal to the voltage (V) divided by the resistance (R), represented by the formula I = V/R. By measuring the voltage across a circuit and knowing the resistance, you can calculate the current flowing through it.
