Question

При прохождении по участку цепи заряда в 10Кл была совершена работа 45 Дж.Чему равна напряжение на этом участке цепи?

Answer 1

Работа A=q*U
U=A/q=45/10=4,5 Дж

Answer 2

Calculating Voltage in a Circuit

To calculate the voltage across a specific segment of a circuit, we can use the formula:

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

Given that the work done (W) is 45 J and the charge (Q) is 10 kC (kiloCoulombs), we can calculate the voltage using the formula above.

Calculation

Using the formula Voltage (V) = Work (W) / Charge (Q), we can calculate the voltage:

Voltage (V) = 45 J / 10 kC

Converting 10 kC to Coulombs: 10 kC = 10,000 C

Voltage (V) = 45 J / 10,000 C

Now, let's calculate the voltage.

Voltage (V) = 0.0045 V

Therefore, the voltage across this segment of the circuit is 0.0045 V.

This calculation is based on the formula for voltage and the given values of work and charge
