Question

R1 = 4 Ом R2 = 7 Ом (пар. соед) Q1 = 280 Дж Q2 = ?

Answer 1

Количество теплоты, выделившееся на проводнике равно работе силы тока, прошедшего через проводник

Answer 2

To find the value of Q2, we need to use the formula for calculating energy:

Q = I^2 * R * t

Where: Q is the energy (in joules) I is the current (in amperes) R is the resistance (in ohms) t is the time (in seconds)

Since you haven't provided any values for the current or time, I cannot calculate the exact value of Q2. If you provide additional information such as the current or time, I can help you calculate Q2.
