  2. Resistors Symbol ( R ) Resistance determines how much current will flow through a component. Resistance is the opposition to Current

  3. Resistors Symbol ( R ) Resistance are used to control voltage and current levels. A very high resistance allows a small amount of current to flow.

  4. Resistors Symbol ( R ) Resistance is synonymous with a pipe for water. The smaller the pipe the more resistance and less water flows. The larger the pipe the less resistance and more water can flow.

  5. Resistors Symbol ( R ) Resistors A very low resistance allows a large amount of current to flow. Resistance is measured in ohms.

  6. Resistors Symbol The unit of resistance is the ohm, which is equal to one volt per ampere, or one volt-second per coulomb.

  7. Resistors Symbol The inverse of resistance, 1/R, is conductance (G), and its SI unit is the siemens (also unofficially called the mho).

  8. Resistors Symbol The voltage measured across a resistor at a given instant is strictly proportional to the current passing through the resistor at that instant.

  9. Resistors (types) Low Power Resistors
