Clearly explain qualitatively why the voltage measured by your voltmeter should be less when you measure the midpoint voltage of the two 10 mq resistors in series compared to the two 10 k12 resistors in series. use words, not equations. b) if your dmm (digital multi-meter) has an internal resistance of 5 m22, calculate the voltage it will measure for these two sets of resistors. 4) explain why connecting your dmm in its "ammeter" setting directly to a power supply will blow the fuse in the dmm. 5) explain how you will determine the internal resistance of your dmm when it is used as an ammeter, and sketch the circuit required. (don't suggest using an ohmmeter; if you simply connect your ammeter to an ohmmeter you will probably blow a fuse.) pick representative values for any resistors that you insert in your circuit, and obtain estimated numerical values for any voltages and currents that you expect to measure. in so doing you should determine if your suggested method is practical.
