NOTE

RESISTOR II

Circuit layouts of a resistors

A resistor typically consists of a small cylindrical body, often made of ceramic or metal, with metallic end caps. The body may be color-coded to indicate its resistance value. Two leads protrude from the end caps, allowing the resistor to be connected within an electrical circuit.

Circuit Components of a resistor

The different circuit components of a resistor include:

  1. Resistance value: Represents how much the resistor opposes the flow of electric current, measured in ohms (Ω).
  2. Power rating: Indicates the maximum amount of power the resistor can dissipate without damage, typically measured in watts (W).
  3. Tolerance: Specifies the maximum deviation from the nominal resistance value, usually expressed as a percentage.
  4. Physical size and shape: Determines the resistor's package type, which can vary from small surface-mount components to larger through-hole resistors.
  5. Temperature coefficient: Indicates how the resistor's resistance changes with temperature, expressed in parts per million per degree Celsius (ppm/°C).

EVALUATION: 1. Identify 5 components of a resistor

  1. Describe the layout of a resistor
