Question

Напряжение на клеммах аккумулятора при разомкнутой цепи равно 36 В, а если через аккумулятор течет ток 2 А, то оно уменьшается до 32 В. Чему равно внутреннее сопротивление аккумулятора?

Answer 1

Ответ:

2 ом,

r = (U1 - U2) / I = (36 - 32)/2 = 4/ 2 = 2Ом

Answer 2

Calculation of Internal Resistance of the Battery

To calculate the internal resistance of the battery, we can use Ohm's Law, which states that the voltage across a resistor is equal to the product of the current flowing through it and the resistance itself.

Given the information provided, we can set up two equations using Ohm's Law:

Equation 1: V1 = I * R Equation 2: V2 = (I - ΔI) * R

Where: - V1 is the voltage across the battery terminals when the circuit is open (36 V) - V2 is the voltage across the battery terminals when a current of 2 A is flowing through it (32 V) - I is the current flowing through the battery (2 A) - ΔI is the change in current (2 A - 0 A = 2 A) - R is the internal resistance of the battery (unknown)

By rearranging Equation 1, we can solve for R:

R = V1 / I

Substituting the given values:

R = 36 V / 2 A = 18 Ω

Therefore, the internal resistance of the battery is 18 Ω.
