what is the function of high resistance R connected with the galvanometer in a potentiometer circuit does this high resistance affect the balance point

Open in App

Solution

Dear Student,

the high resistance with the galvanometer is just to limit the current through the galvanometer when the voltage across the galvanometer is high because the internal resistance of the galvanometer is very low for high PD it can burn . so we put high resistance to keep it safe . it doesn't effect the balance point .

Q. Assertion :In meter bridge experiment, a high resistance is always connected in series with a galvanometer. Reason: As resistance increases, current through the circuit increases.

Figure 3.33 shows a potentiometer with a cell of 2.0 V and internal resistance 0.40 Ω maintaining a potential drop across the resistor wire AB. A standard cell which maintains a constant emf of 1.02 V (for very moderate currents up to a few mA) gives a balance point at 67.3 cm length of the wire. To ensure very low currents drawn from the standard cell, a very high resistance of 600 kΩ is put in series with it, which is shorted close to the balance point. The standard cell is then replaced by a cell of unknown emf ε and the balance point found similarly, turns out to be at 82.3 cm length of the wire.

(a) What is the value ε ?

(b) What purpose does the high resistance of 600 kΩ have?

(d) Is the balance point affected by the internal resistance of the driver cell?

(e) Would the method work in the above situation if the driver cell of the potentiometer had an emf of 1.0 V instead of 2.0 V?

(f ) Would the circuit work well for determining an extremely small emf, say of the order of a few mV (such as the typical emf of a thermo-couple)? If not, how will you modify the circuit?

The emf of the cell is 2V and its internal resistance is 2 ohm. A resistance of 8 ohm is joined to the battery in parallel. This is connected is the secondary circuit of the potentiometer. If 1V standard cell balances for 100 cm of potentiometer wire, the balance point of the above cell is :
