Figure 2.2 shows a DMM that can be connected across a power supply to measure its voltage. Assume that having measured voltage, you now wish to measure the power supply resistance. Explain why care is required when changing the DMM setting from resistance to voltage and suggest a procedure to avoid experiencing problems.
