SUMMARY

A moving coil meter can be converted into an ohmmeter by utilizing a series configuration that incorporates a known resistor. This method allows for the measurement of resistance based on the deflection of the meter's needle. The discussion highlights the importance of understanding the principles behind the Darsonval movement, which is essential for accurate conversions. For further details, users are directed to resources such as Engineers Edge for foundational knowledge.
