One ohm of resistance exists when a crystal-clear one volt of pressure pushes one ampere of current through a conductor. Why Does Resistance Matter?
Not all materials are equal. Conductors (like copper) have very low resistance, while insulators (like rubber) have extremely high resistance. Common Multiples
Resistance converts electrical energy into heat. This is how your toaster, electric stove, and space heater work.
The ohm is defined by , which is usually written as: V = I × R V = Voltage (Volts) I = Current (Amperes) R = Resistance (Ohms)
