Question

Сила тока в цепи 0,7 А, напряжение на одном из ее участков 50 В. Какую работу совершает электрический ток на этом участке за 10 мин?

Answer 1

A=I*U*t=0,7*50*600=21 000 Дж                                      

Answer 2

Calculation of Work Done by Electric Current

To calculate the work done by an electric current, we need to use the formula:

Work (W) = Current (I) × Voltage (V) × Time (t)

Given: - Current (I) = 0.7 A - Voltage (V) = 50 V - Time (t) = 10 min = 10 × 60 = 600 s

Using the formula, we can calculate the work done by the electric current on this section of the circuit:

W = I × V × t = 0.7 A × 50 V × 600 s

Let's calculate the value:

W = 0.7 A × 50 V × 600 s = 21,000 J

Therefore, the work done by the electric current on this section of the circuit over a period of 10 minutes is 21,000 Joules.
