A simple ohmmeter is constructed using a battery, a galvanometer, and a set of resistors. The battery supplies a constant voltage, while the galvanometer measures the current flowing through the circuit when a resistor is connected. The resistance is calculated using Ohm's Law (R = V/I), where V is the battery voltage and I is the current indicated by the galvanometer. The device may also include a scale or a dial to provide a direct reading of resistance values.
Anderson's Bridge is an AC bridge. It is used to measure self inductance of a coil using a capacitor and resistors. The bridge continuously balances itself by a steady current through a moving coil galvanometer replacing a headphone and a battery replacing an A.C. source. The resistance is adjusted until the currents two specific resistors in the center of the arrange are the same. Then inductive balance is achieved by using the A.C. source and headphone in their respective positions.
There are lots and types of battery
Its the CR2032 battery
It's what happens when a battery is about to expire.
Ohms are the unit of measurement for resistance, so an ohmmeter is a device that measures electrical resistance. A galvanometer measures the current flowing through the resistance, so the two are related. To convert a galvanometer into an ohmmeter, one needs an external battery.
By using wheatstone bridge principle we can proceed to find the phase to phase fault's.i:e the wheatstone bridge is mainly used to find the resistances/inductance/capacitances.it is mainly consists of 4 resistances like this(<>)& having a galvanometer in centre&a battery is connected to it. when ever the current flowing through the galvanometer is zero by varying the one resistance,then the ratio of two resistances connected at one end is equal to other two resistances ratio.By using the same principle ,one phase is connected to known resistance and a good cable is shorted to the fault cable.and other resistane is connected to the good cable&a galvanometer is connected to it.by varying the resistances the galvanometer shows null reading.then bridge is balanced & by using bridge equation we can solve to find the distance where the error is located
the principle of wheatstone bridge is,there is a potential fall is directly proportional to the length of the wire, and this fall is also equalt to the fall accross the resistances applied in parallel to the battery. It is a form of wheatstone bridge.

Just connect a resistor and a small battery in series with the galvanometer,change the markings on the meter's scale, and you have an ohmmeter.
I think that you talk about the usage of galvanometer in photoelectric emission experiment. Right? The main purpose of using a galvanometer is to know about whether current flows or not and also the direction in which current flows. Moreover current flows right from anode to cathode and electrons do flow from cathode to anode within the discharge tube.
The two batteries may look the same but have slightly different power outputs. Interchanging them could damage the device by putting out to much or to little power.
the battery will no longer work.

It's in the trunk ( in order better to balance the weight, fore and aft.)
The optimal battery acid concentration for maximizing performance and longevity of a battery is typically around 30-35 sulfuric acid. This concentration helps to balance the electrolyte levels and maintain proper chemical reactions within the battery, leading to better overall performance and lifespan.
About 60% of the weight of an automotive-type lead-acid battery rated around 60 Ah (8.7 kg of a 14.5 kg battery) is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. (Wikipedia)
