Question

Через проводник за время 10с прошел заряд 24 Кл.Напряжение на нем составило 12В.Определить работу тока,мощность тока,сопротивление проводника

Answer 1

T=10 c    q=24 Кл    U=12 B    A=?    N=?    R=?
===
I=q/t
A=I*U*t=q*U=24*12=288 Дж
N=A/t=288/10=28.8 Вт
R=U/I=U*t/q=12*10/24=5 Ом
=========================

Answer 2

Given Information:

- Time (t) = 10 s - Charge (Q) = 24 C - Voltage (V) = 12 V

Calculating Work Done by Current:

The work done by an electric current can be calculated using the formula:

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

Substituting the given values:

Work (W) = 24 C x 12 V

Calculating the work done:

Work (W) = 288 J

Therefore, the work done by the current is 288 Joules.

Calculating Power of the Current:

The power of an electric current can be calculated using the formula:

Power (P) = Work (W) / Time (t)

Substituting the given values:

Power (P) = 288 J / 10 s

Calculating the power:

Power (P) = 28.8 W

Therefore, the power of the current is 28.8 Watts.

Calculating Resistance of the Conductor:

The resistance of a conductor can be calculated using Ohm's Law:

Resistance (R) = Voltage (V) / Current (I)

Since the current is not given, we need to calculate it using the formula:

Current (I) = Charge (Q) / Time (t)

Substituting the given values:

Current (I) = 24 C / 10 s

Calculating the current:

Current (I) = 2.4 A

Now, substituting the current value into the resistance formula:

Resistance (R) = 12 V / 2.4 A

Calculating the resistance:

Resistance (R) = 5 Ω

Therefore, the resistance of the conductor is 5 Ohms.

To summarize: - The work done by the current is 288 Joules. - The power of the current is 28.8 Watts. - The resistance of the conductor is 5 Ohms.
