Choose the statements that are true/correct about instruments used in circuits.    The ammeter is connected along the circuit. The ammeter is used to determine the resistance. The black electrode of the voltmeter must be placed nearer the positive terminal of the battery. A positive reading in the voltmeter means that the red electrode is placed near the positive terminal and the black electrode on the negative terminal of the battery. The voltmeter is connected across the resistor to determine the voltage drop. The red electrode of the voltmeter must be placed nearer the positive terminal of the battery.

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.
