Question

Сила тока текущего по проводнику сопротивлением 6 ом равна 2 а каково напряжение на концах проводника как изменится сила тока в данном проводнике если напряжение на его концах увеличится в 4 раза

Answer 1

Ответ: 12В; 8А

Объяснение:

Дано:

R=6 Ом

I1=2А

U2=4U1

----------

U1-?; I2-?

U1=I1*R=2*6=12В

U2=4U1=4*12=48В

I2=U2/R=48/6=8А

Answer 2

Calculation of Voltage and Current

To calculate the voltage and current in a conductor with a resistance of 6 ohms and a current of 2 amps, we can use Ohm's Law. Ohm's Law states that the voltage across a conductor is equal to the current flowing through it multiplied by the resistance of the conductor.

The formula for Ohm's Law is:

V = I * R

Where: - V is the voltage across the conductor, - I is the current flowing through the conductor, and - R is the resistance of the conductor.

In this case, the resistance (R) is given as 6 ohms and the current (I) is given as 2 amps. Let's calculate the voltage (V):

V = 2 A * 6 Ω = 12 V

Therefore, the voltage across the conductor is 12 volts.

Effect of Increasing Voltage on Current

If the voltage across the conductor increases by a factor of 4, we can determine the effect on the current using Ohm's Law. Since the resistance remains the same, we can rearrange Ohm's Law to solve for current:

I = V / R

Where: - I is the current flowing through the conductor, - V is the voltage across the conductor, and - R is the resistance of the conductor.

In this case, the voltage (V) has increased by a factor of 4, so the new voltage is 12 V * 4 = 48 V. The resistance (R) remains 6 ohms. Let's calculate the new current (I):

I = 48 V / 6 Ω = 8 A

Therefore, if the voltage across the conductor increases by a factor of 4, the current flowing through the conductor will increase to 8 amps.

Please note that the calculations provided are based on the information given and the application of Ohm's Law.
