How do you calculate the resistance of R?

Anonymous

∙ 16y ago

Updated: 11/2/2022

In electronics, R or resistance is calculated by dividing the voltage by the current, or I/E

Here's a good Ohms law chart; http://www.the12volt.com/ohm/ohmslaw.asp

How do you calculate contact resistance?

Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.

How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?

Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.

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 do you calculate current required?

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 .

How do you calculate the resistance of a heater element that's uses 220v and draws 11amps?

The equation you are looking for is R = E/I.

What quantities are needed to calculate an object's resistance?

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 = ρ * (L/A) to calculate the resistance, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
