How do you find resistance in physics?

Quick Summary. To calculate total resistance in series circuits, look for a single loop with no branching paths. Add all of the resistances across the circuit together to calculate the total resistance. If you don’t know the individual values, use the Ohm’s Law equation, where resistance = voltage divided by current.

What is the scientific definition of resistance?

Resistance is the opposition that a substance offers to the flow of electric current . It is represented by the uppercase letter R. When an electric current of one ampere passes through a component across which a potential difference ( voltage) of one volt exists, then the resistance of that component is one ohm.

What is the meaning of resistance?

Resistance is defined as a refusal to give in or to something that slows down or prevents something. An example of resistance is a child fighting against her kidnapper.
