The correct choice is (1). When a bulb and a heater are connected in parallel and this combination is connected across the mains, potential difference across each is the same equal to the voltage V of the mains, irrespective of the resistance of the bulb. If R is the resistance of the heater, the rate at which heat is produced will be V2/R in both cases.

Directions:In the following question, Statement - 1 (Assertion) is fol...
Statement - 1: A 60 W bulb is connected in parallel with a room heater and this combination is connected across the mains. If the 60 W bulb is replaced by a 100 W bulb, the heat produced by the heater will remain the same.
Statement - 2: When resistances are connected in parallel across the mains, the heat produced is inversely proportional to the resistance.
To understand whether Statement 1 and Statement 2 are true and if Statement 2 is a correct explanation for Statement 1, let's analyze each statement individually and then evaluate their relationship.
Statement - 1: A 60 W bulb is connected in parallel with a room heater and this combination is connected across the mains. If the 60 W bulb is replaced by a 100 W bulb, the heat produced by the heater will remain the same.
This statement is true. When the bulbs are connected in parallel, they share the same voltage across them. The power consumed by each bulb is given by the formula P = V^2/R, where P is the power, V is the voltage, and R is the resistance. Since the voltage across the bulbs remains the same, the power consumed by each bulb depends on their respective resistances. Therefore, replacing the 60 W bulb with a 100 W bulb will not affect the heat produced by the room heater.
Statement - 2: When resistances are connected in parallel across the mains, the heat produced is inversely proportional to the resistance.
This statement is also true. When resistances are connected in parallel, the total resistance decreases. According to Ohm's Law, V = IR, where V is the voltage, I is the current, and R is the resistance. Since the voltage across the resistances remains the same, the current flowing through the resistances increases as the total resistance decreases. The power consumed by each resistance is given by the formula P = I^2R. As the current increases, the power consumed by each resistance increases. Therefore, the heat produced is directly proportional to the resistance.
Now let's evaluate the relationship between Statement 1 and Statement 2.
Statement 2 explains why the heat produced by the room heater remains the same when the 60 W bulb is replaced by a 100 W bulb. Since the voltage across the bulbs remains the same, the power consumed by each bulb depends on their respective resistances. As explained in Statement 2, the heat produced is inversely proportional to the resistance. Therefore, Statement 2 is a correct explanation for Statement 1.
Hence, the correct answer is option A: Statement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.
Statement - 2: When resistances are connected in parallel across the mains, the heat produced is inversely proportional to the resistance.
To understand whether Statement 1 and Statement 2 are true and if Statement 2 is a correct explanation for Statement 1, let's analyze each statement individually and then evaluate their relationship.
Statement - 1: A 60 W bulb is connected in parallel with a room heater and this combination is connected across the mains. If the 60 W bulb is replaced by a 100 W bulb, the heat produced by the heater will remain the same.
This statement is true. When the bulbs are connected in parallel, they share the same voltage across them. The power consumed by each bulb is given by the formula P = V^2/R, where P is the power, V is the voltage, and R is the resistance. Since the voltage across the bulbs remains the same, the power consumed by each bulb depends on their respective resistances. Therefore, replacing the 60 W bulb with a 100 W bulb will not affect the heat produced by the room heater.
Statement - 2: When resistances are connected in parallel across the mains, the heat produced is inversely proportional to the resistance.
This statement is also true. When resistances are connected in parallel, the total resistance decreases. According to Ohm's Law, V = IR, where V is the voltage, I is the current, and R is the resistance. Since the voltage across the resistances remains the same, the current flowing through the resistances increases as the total resistance decreases. The power consumed by each resistance is given by the formula P = I^2R. As the current increases, the power consumed by each resistance increases. Therefore, the heat produced is directly proportional to the resistance.
Now let's evaluate the relationship between Statement 1 and Statement 2.
Statement 2 explains why the heat produced by the room heater remains the same when the 60 W bulb is replaced by a 100 W bulb. Since the voltage across the bulbs remains the same, the power consumed by each bulb depends on their respective resistances. As explained in Statement 2, the heat produced is inversely proportional to the resistance. Therefore, Statement 2 is a correct explanation for Statement 1.
Hence, the correct answer is option A: Statement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.
