Question

Через провідник, на кінцях якого напруга 24 В за 15 хв пройшов електричний заряд 90 Кл. Який опір провідника? (Это задачка)

Answer 1

Ответ: 240 Ом

Объяснение:

15хв=15*60=900 с

I=q/t=90 Кл/ 900 с = 0,1 А

I=U/R виразимо R, R=U/I=24 В/ 0,1 А = 240 Ом (за законом Ома)

Answer 2

Calculating the Resistance of the Conductor

To calculate the resistance of the conductor, we can use the formula:

Resistance (R) = Voltage (V) / Charge (Q)

Given: - Voltage (V) = 24 V - Charge (Q) = 90 kC (kiloCoulombs)

Using the given values, we can calculate the resistance of the conductor.

Step 1: Convert the charge from kiloCoulombs to Coulombs. 90 kC = 90,000 C

Step 2: Use the formula to calculate the resistance. Resistance (R) = Voltage (V) / Charge (Q) Resistance (R) = 24 V / 90,000 C

Step 3: Calculate the resistance. Resistance (R) = 0.0002667 ohms

Therefore, the resistance of the conductor is approximately 0.0002667 ohms.
