A voltmeter of internal resistance of 2002 and current rating of 40mA is being used to measure Fisk voltages up to 300V. As part of design work, you consider four resistors for use as series resistors to extend the range of measurable voltages by the voltmeter. In your initial work, you considered resistances: 2002, 2002, 200052, 20,0002 and 200,00002. From first principles, derive an expression for insertion error and tabulate insertion errors obtained with the five series resistors considered.

The total charge a battery can supply is rated in mAh, the product of the current (in mA) and the time (in h) that the battery can provide this current. A battery rated at 1000 mA-hr can supply a current of 1000 mA for 1.0 h, 500 mA current for 2.0 h, and so on. A typical AA rechargeable battery has a voltage of 1.2 V and a rating of 1800 mA-h.
