Question

Помогите братцы!!! P = 500 Bt U = 127 B t = 30 мин найти I, R, A

Answer 1

P=I*U
I=P/U=500/127=3,94 А
R=U^2/P=16129/1000=16 Ом
A=P*t=500*30*60=9*10^5 Дж

Answer 2

Calculation of I, R, and A

To calculate the values of I, R, and A based on the given information, we need to understand the meaning of each variable:

- P: Represents the power in watts (W). - U: Represents the voltage in volts (V). - t: Represents the time in minutes (min).

The formulas for calculating I (current), R (resistance), and A (charge) are as follows:

1. Current (I) can be calculated using Ohm's Law: I = P / U. 2. Resistance (R) can be calculated using the formula: R = U / I. 3. Charge (A) can be calculated using the formula: A = I * t.

Given the following values: - P = 500 W - U = 127 V - t = 30 min

Let's calculate I, R, and A step by step:

1. Calculate the current (I): - I = P / U - I = 500 W / 127 V - I ≈ 3.9370 A

2. Calculate the resistance (R): - R = U / I - R = 127 V / 3.9370 A - R ≈ 32.2308 Ω

3. Calculate the charge (A): - A = I * t - A = 3.9370 A * 30 min - A ≈ 118.1100 C

Therefore, based on the given values, the calculated values are: - Current (I) ≈ 3.9370 A - Resistance (R) ≈ 32.2308 Ω - Charge (A) ≈ 118.1100 C

Please note that the calculations are approximate due to rounding.
