Part II: The potential difference across different elements of a circuit resistance in series 1. Using the circuit shown below, set R1 and R2 as shown in the chart below. For each pair of resistances in the chart below, record the drop in voltage, or potential, across R1 (Figure a), drop in voltage, or potential, across R2 (Figure b), then record it across both resistors (Figure c).

A 0 – 150 voltmeter has a resistance of 2000-ohms per volt.  It is desired to change this voltmeter to a 0 – 600 volt instrument by the edition of an external multiplier. What is the resistance, in ohms, of this external multiplier?

Your job is to order and connect lead-acid cells used to supply an uninterruptible power supply (UPS). The battery output voltage must be 126 V and have a current capacity of not less than 250 A-hr. Each cell has a rating of 2 V and 100 A-hr. How many cells must be ordered and how would you connect them?

Please break this down for me as much as possible, im struggling to grasp kirchhoff's, thank you.

A galvanometer with a internal resistance of 400 and a shunt resistor of value 'Rsh' is connected in series with a 100 resistor. A constant voltage VO' is applied aoross the oircuit, and the galvanometer deflects a certain amount. The shunt resistor is then removed, and replaced in series with the 100 resistor. With the same voltage 'VO', the galvanometer deflection is unchanged. Calculate the value 'Rsh' of the shunt resistor.
