In shunt type ohmmeter, full-scale deflection current indicator is marked as

  • In shunt type ohmmeter, full-scale deflection current indicator is marked as Infinite.
  • In a shunt type ohmmeter, the full-scale deflection current indicator is marked as "Infinite" because the shunt resistor used in the meter is designed to have a very low resistance compared to the resistance being measured.
  • The shunt resistor is connected in parallel with the meter, and most of the current flows through the shunt resistor, bypassing the meter.
  • Only a small fraction of the current passes through the meter, and the amount of current that passes through the meter depends on the resistance being measured.
  • The meter is calibrated so that when the resistance being measured is equal to the shunt resistor, the full-scale deflection current flows through the meter.
  • If the shunt resistor has a very low resistance, the current that flows through the meter at full-scale deflection will be very high, approaching infinity.
