Question

Через поперечний переріз провідника за 2 хв проходить заряд 600 Кл. Чому дорівнює опір провідника, якщо напруга на його кінцях дорівнює 2,5 В.

Answer 1

Ответ:

2,5 Ом

Объяснение:
2 мин = 120 с

I=q/t=600/120=5 A
I=U/R.
R=U/I=2,5/5=0,5 Ом

Answer 2

Calculation of Resistance in the Conductor

To calculate the resistance in the conductor, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) between them. The formula for Ohm's law is:

V = I * R

Where: - V = Voltage across the conductor (2.5 V) - I = Current passing through the conductor (to be calculated) - R = Resistance of the conductor (to be calculated)

We are given the charge passing through the conductor and the time taken. Using the formula for current (I = Q / t), where Q is the charge and t is the time, we can calculate the current passing through the conductor.

Given: - Charge (Q) = 600 kC (600,000 C) - Time (t) = 2 minutes = 120 seconds

Calculation of Current

Using the formula I = Q / t, we can calculate the current passing through the conductor: I = Q / t = 600,000 C / 120 s = 5000 A

Calculation of Resistance

Now, using Ohm's law (V = I * R), we can calculate the resistance of the conductor: R = V / I = 2.5 V / 5000 A = 0.0005 ohms

Therefore, the resistance of the conductor, given the voltage across its ends is 2.5 V and the charge passing through it in 2 minutes is 600 kC, is 0.0005 ohms.
