Question

Найти количество теплоты, выделившееся в проводнике сопротивлением 20 Ом при напряжении 100 В за 10 минут работы электрической цепи.

Answer 1

Дано:                           Q=I(в квадрате)Rt        
R=20 Oм                       I=U/R
U=100 B(600с)              I=100/20=5
t=10 мин                       Q=5(в квадрате)*20*600=300000
Найти:Q-?

Answer 2

Q=U^2*t/R
Q=10000*10/20=5000 Дж

Answer 3

Calculating Heat Produced in the Conductor

To find the amount of heat produced in the conductor, we can use the formula:

Q = I^2 * R * t

Where: - Q = heat produced (in joules) - I = current (in amperes) - R = resistance (in ohms) - t = time (in seconds)

Given: - Resistance (R) = 20 ohms - Voltage (U) = 100 V - Time (t) = 10 minutes = 600 seconds

First, we need to find the current (I) using Ohm's law: U = I * R So, I = U / R

Let's calculate the current (I): I = U / R = 100 V / 20 ohms = 5 A

Now, we can calculate the heat produced (Q): Q = I^2 * R * t = (5 A)^2 * 20 ohms * 600 s = 500 * 20 * 600 = 6,000,000 joules

Therefore, the amount of heat produced in the conductor is 6,000,000 joules.
