Two resistance thermometers are made, one of the platinum wire and the other of germanium wire. The resistance of both the thermometers are equal at room temperature. The two resistance wires are connected to a battery. Now the two resistance wires are heated to 100oC. The potential drop in the two resistance is measured. Which of the following statement is correct
- a)The potential drop across the platinum wire is eqaul to the potential drop across the germanium wire
- b)The potential drop across the platinum wire is greater than that acorss germanium
- c)The potential drop across the platinum wire is less than that across germanium
- d)The nature of the potential drop cannot be ascertained unless the magnitude of the current is known
Correct answer is option 'B'. Can you explain this answer?

With rise in temp, the resistance of platinum wire increases but of germanium wire decreases.
Since the current is same in the wires, when connected in series, therefore heat produced ∝ R

Explanation:
Platinum vs. Germanium Resistance Thermometers:
- Resistance thermometers made of platinum and germanium wires have equal resistance at room temperature.
Heating to 100°C:
- When both resistance wires are heated to 100°C, their resistance changes due to the temperature coefficient of resistance.
Potential Drop Measurement:
- The potential drop across a resistor is directly proportional to its resistance and the current passing through it, according to Ohm's Law (V = IR).
- Since the resistance of the platinum wire is greater than that of the germanium wire at 100°C, the potential drop across the platinum wire will be greater than that across the germanium wire.
Therefore, the correct statement is:
The potential drop across the platinum wire is greater than that across germanium.
