Calculation of Current in the Second Conductor

To determine the current in the second conductor, we can use the principle of parallel circuits. In a parallel circuit, the voltage across each branch is the same, while the total current is divided among the branches.

Given: - Current in the first conductor (I1) = 0.5 A - Resistance of the circuit segment (R) = 30 Ω

To find the current in the second conductor (I2), we can use the formula:

I2 = (I1 * R1) / R2

Where: - I2 is the current in the second conductor - I1 is the current in the first conductor - R1 is the resistance of the first conductor - R2 is the resistance of the second conductor

Since the resistance of the circuit segment is given as 30 Ω, we can assume that the resistance of each conductor is equal. Therefore, R1 = R2 = 30 Ω.

Substituting the given values into the formula, we have:

I2 = (0.5 A * 30 Ω) / 30 Ω

Simplifying the equation, we find:

I2 = 0.5 A

Therefore, the current in the second conductor is 0.5 A.

Calculation of Voltage and Resistance

To determine the voltage across the circuit segment and the resistance of each conductor, we can use Ohm's Law.

Ohm's Law states that the voltage (V) across a circuit element is equal to the current (I) flowing through it multiplied by the resistance (R) of the element.

Given: - Current in the first conductor (I1) = 0.5 A - Resistance of the circuit segment (R) = 30 Ω

To find the voltage across the circuit segment (V), we can use the formula:

V = I * R

Substituting the given values into the formula, we have:

V = 0.5 A * 30 Ω

Simplifying the equation, we find:

V = 15 V

Therefore, the voltage across the circuit segment is 15 V.

Since the resistance of each conductor is equal, we can divide the total resistance of the circuit segment by the number of conductors to find the resistance of each conductor.

Resistance of each conductor = R / 2

Substituting the given value of R into the formula, we have:

Resistance of each conductor = 30 Ω / 2

Simplifying the equation, we find:

Resistance of each conductor = 15 Ω

Therefore, the resistance of each conductor is 15 Ω.

In summary: - The current in the second conductor is 0.5 A. - The voltage across the circuit segment is 15 V. - The resistance of each conductor is 15 Ω.
