16.1: EandM- Ohm's Law

  • Page ID
  • The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. It is measured in Ohms and the relation between resistance (\(R\)), current (\(I\)) and electrical potential (\(V\)) is Ohm's law: \(V = IR\). Ohm's law says that a larger voltage makes more current flow if resistance is fixed. Or if resistance is lower at the same voltage, more current will flow.
