The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X

The formula for calculating the resistance of a capacitor is R 1 / (2 f C), where R is the resistance in ohms, f is the frequency in hertz, and C is the capacitance in farads.
The symbol of the quantity resistance is an italicised upper-case 'R'.
1/specific resistance
The formula to find resistance force is given by R = F/A, where R is the resistance force, F is the force applied, and A is the area over which the force is applied. This formula is often used in physics and engineering to determine the resistance force in various scenarios.
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
The maximum voltage formula for a circuit is V I R, where V is the voltage, I is the current, and R is the resistance.
