Question

Для прохождения по проводнику Эл.заряда 16Кл, электрическое поле совершает работу 0,8 кДж. Определите напряжение на концах участка проводника ​

Answer 1

Напряжение U — это работа, которую совершает электрическое поле для премещения заряда 1 Кл.

U = A/q

q = 16 Кл

A = 0,8 кДж = 800 Дж

U = 800/16 = 50 (вольт)

Answer 2

Calculation of Voltage

To determine the voltage across a segment of a conductor, we can use the formula:

Voltage (V) = Work done (W) / Charge (Q)

In this case, we are given that the work done is 0.8 kJ (kilojoules) and the charge is 16 kC (kilocoulombs). We need to convert the work done from kilojoules to joules and the charge from kilocoulombs to coulombs before plugging the values into the formula.

Converting 0.8 kJ to joules: 0.8 kJ = 0.8 * 1000 J = 800 J

Converting 16 kC to coulombs: 16 kC = 16 * 1000 C = 16000 C

Now we can calculate the voltage:

V = W / Q = 800 J / 16000 C = 0.05 V

Therefore, the voltage across the segment of the conductor is 0.05 volts.
