Expression for the heat produced in a conductor:

When a current I flows through a conductor of resistance R for time t, the heat produced in the conductor can be calculated using the formula:

Q = I^2 * R * t

Where:
Q is the heat produced (in joules),
I is the current flowing through the conductor (in amperes),
R is the resistance of the conductor (in ohms), and
t is the time for which the current flows (in seconds).

Case 1: Two identical resistors connected in series

When two identical resistors of resistance R are connected in series with a battery of potential difference V for time T, the current flowing through each resistor can be calculated using Ohm's Law:

I = V / (2R)

Where:
I is the current flowing through each resistor (in amperes),
V is the potential difference across the series combination (in volts), and
2R is the total resistance of the series combination (since the resistors are identical).

The heat produced in each resistor can be calculated using the formula mentioned above:

Q1 = (V / (2R))^2 * R * T = V^2 * T / (4R)

Case 2: Two identical resistors connected in parallel

When the two identical resistors of resistance R are connected in parallel with the same battery for the same time T, the potential difference across each resistor remains the same as the battery's potential difference V.

The total resistance of the parallel combination can be calculated using the formula:

1/Rp = 1/R + 1/R = 2/R

Where:
1/Rp is the reciprocal of the total resistance of the parallel combination (in inverse ohms),
1/R is the reciprocal of the resistance of each resistor (since they are identical), and
2/R is the sum of the reciprocals of the resistances.

The current flowing through each resistor in parallel can be calculated using Ohm's Law:

I = V / Rp = V / (2R)

The heat produced in each resistor can be calculated using the formula mentioned above:

Q2 = (V / (2R))^2 * R * T = V^2 * T / (4R)

Comparison of the heat produced in two cases:

As we can see, the heat produced in both cases is the same, given by the expression V^2 * T / (4R). This implies that the arrangement of resistors (series or parallel) does not affect the total heat produced. The heat generated is solely determined by the potential difference across the resistors, the total resistance, and the time for which the current flows.
