ELECTRIC CURRENT AND DIRECT CURRENT CIRCUIT GettyImages-144635668…

- - - - Depends on:
        
        Type of material it is made
        
        Its length (L)
        
        Its cross-sectional area (A)
        
        Its temperature (T)
      - SI unit: Ohm (Ω) @ V/A
      - Property which opposes or limits current
    - - Known as specific resistance
        
        A good electric conductor have a very low resistivity
        
        Good insulators have very high resistivity.
        
        Depends on the length and cross-sectional area.
      - SI unit: Ohm meter (Ωm)
    - - The voltage drop across a conductor, V is proportional to the current, I through
        it if its physical conditions & temperature are constant
- - - - Shunt (Pemirau)
        A shunt resistor Rs in
        parallel
      - Multiplier (Pendarab)
        A multiplier resistor Rm in series
