Question

По проводнику сопротивление 5 Ом за 1,5 мин прошло 45Кл электричества. Найдите напряжение,Приложенное к концам проводникам!

Answer 1

Зная, что сила тока это заряд разделить на время I =q / t . вычислим силу тока:
I=45 / 90=0,5A. ( 1,5мин=90с) .
По закону Ома для участка цепи I = U / R . выразим напряжение U.
U=I*R . U=0,5*5=2,5В.
U=2,5B.

Answer 2

Calculation of Voltage

To find the voltage applied to the ends of the conductor, we can use Ohm's Law, which states that the voltage (V) is equal to the product of the current (I) and the resistance (R). Mathematically, this can be expressed as:

V = I * R

Given that the resistance of the conductor is 5 Ohms and the amount of charge that passed through the conductor is 45,000 Coulombs, we need to find the current.

Calculation of Current

To find the current, we can use the formula:

I = Q / t

Where Q is the charge and t is the time. In this case, the charge is 45,000 Coulombs and the time is 1.5 minutes (or 90 seconds).

Substituting the values into the formula, we get:

I = 45,000 C / 90 s = 500 A

Now that we have the current, we can calculate the voltage.

Calculation of Voltage (continued)

Using Ohm's Law, we can substitute the values of the current and resistance into the formula:

V = I * R = 500 A * 5 Ω = 2500 V

Therefore, the voltage applied to the ends of the conductor is 2500 Volts.
