Question

Чему равна сила тока аккумулятора с эдс 12 вольт и внутренним сопротивлением 0,01 ом если к нему подключили лампочку сопротивлением 10 ом

Answer 1

Сила тока по закону Ома равна I=E/(R+r)=12/(10+0,01)= 1,199 А. Здесь E- значение ЭДС, R- значение сопротивления лампочки,  r- значение внутреннего сопротивления аккумулятора.

Ответ: 1,199 А.

Answer 2

Calculating Current in a Circuit with a Battery and a Light Bulb

To calculate the current in a circuit with a battery and a light bulb, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) between them. The formula for Ohm's law is:

I = V / R

Where: - I = current in amperes (A) - V = voltage in volts (V) - R = resistance in ohms (Ω)

Given: - EDS (electromotive force) of the battery = 12 volts - Internal resistance of the battery = 0.01 ohms - Resistance of the light bulb = 10 ohms

Calculating the Total Resistance in the Circuit

The total resistance in the circuit can be calculated using the formula for resistors in series, which states that the total resistance (R_total) of resistors connected in series is the sum of the individual resistances.

R_total = R_internal + R_bulb

Where: - R_internal = internal resistance of the battery - R_bulb = resistance of the light bulb

R_total = 0.01Ω + 10Ω = 10.01Ω

Calculating the Current in the Circuit

Now, we can use Ohm's law to calculate the current flowing through the circuit.

I = V / R_total

Substituting the given values: I = 12V / 10.01Ω = 1.1988A

Therefore, the current in the circuit when the 12V battery with an internal resistance of 0.01Ω is connected to a 10Ω light bulb is approximately 1.1988 amperes.
