Question

Через спираль электрической лампы за 10 с прошло 15 Кл электричества, при этом была совершена работа 45 дж. Чему равна сила тока и напряжение на этом участке электрической цепи. СДЕЛАЙТЕ ПОЖАЛУЙСТА ОЧЕНЬ НАДО

Answer 1

I=15/10 = 1,5 А

A=45*15=675

Answer 2

Calculation of Current and Voltage in the Electric Circuit

To calculate the current and voltage in the given electric circuit, we need to use the formulas related to electrical energy and electrical work.

The electrical work done in a circuit is given by the formula:

W = QV

Where: - W is the work done (in joules) - Q is the charge (in coulombs) - V is the voltage (in volts)

In this case, the work done is 45 J and the charge is 15 C. We need to find the current (I) and voltage (V) in the circuit.

Using the formula for work done, we can rearrange it to find the voltage:

V = W / Q

Substituting the given values:

V = 45 J / 15 C

Simplifying the equation:

V = 3 V

Therefore, the voltage on this section of the electric circuit is 3 volts.

To find the current, we can use Ohm's Law, which states that the current (I) flowing through a conductor is equal to the voltage (V) divided by the resistance (R):

I = V / R

However, since the resistance is not given in the question, we cannot directly calculate the current using Ohm's Law.

Unfortunately, the provided search results do not contain the necessary information to determine the resistance or provide an alternative method to calculate the current. Therefore, we cannot determine the value of the current in this specific case.

Please note that the calculation of current and voltage in an electric circuit depends on various factors, including the resistance and the specific configuration of the circuit. Without additional information, it is not possible to provide a more accurate answer.
