Question

Срочно!! Даю 20 баллов При напрузі 110 В, підведеному до резистору, сила струму в ньому дорівнює 5А. Яка буде сила струму в резисторі, якщо напругу на ньому збільшити на 10 В?

Answer 1

Ответ:

5,45 А

Объяснение:

I = V/R

Подставляем, что в дано

5=110/R

R=22

Подставляем напряжение

I=120/22

I = 5,454545 = 5,45

Answer 2

To calculate the new current in the resistor when the voltage across it is increased by 10V, we can use Ohm's Law. Ohm's Law states that the current flowing through a resistor is directly proportional to the voltage across it and inversely proportional to its resistance.

The formula for Ohm's Law is:

I = V / R

Where: - I is the current (in Amperes) - V is the voltage (in Volts) - R is the resistance (in Ohms)

In this case, we are given that the voltage across the resistor is initially 110V and the current flowing through it is 5A. We need to find the new current when the voltage is increased by 10V.

Let's calculate the resistance of the resistor using the initial voltage and current:

R = V / I

R = 110V / 5A

R = 22 Ohms [[1]]

Now, we can calculate the new current using the new voltage and the resistance we just calculated:

I_new = (V + 10V) / R

I_new = (110V + 10V) / 22 Ohms

I_new = 120V / 22 Ohms

I_new ≈ 5.45A [[1]]

Therefore, the new current in the resistor, when the voltage across it is increased by 10V, will be approximately 5.45 Amperes.

Please note that this calculation assumes that the resistance of the resistor remains constant.
