Question

Аккумулятор с ЭДС 6 В и внутренним сопротивлением 0,1 Ом питает внешнюю цепь сопротивлением 11,9 Ом. Какое количество теплоты выделится за 10 мин во всей цепи?

Answer 1

Согласно закону Ому для замнкутого участка цепи I=Е/R+r,а количество теплоты по закону Джоуля-Ленца Q=I^2rt,тогда на внутреннем уровне будет равно Q1=I^2Rt и на внешнем Q2=I^2rt.Полное Q=Q1+Q2=I^2rt+I^2Rt=I^2(R+r)t=t×E^2/R+r=600 ×36/11,9+0,1=1800Дж=1,8 кДж

Answer 2

Calculation of Heat Generated in the Circuit

To calculate the amount of heat generated in the circuit, we need to use the formula:

Q = I^2 * Z * t

Where: - Q is the amount of heat generated in Joules (J) - I is the current flowing through the circuit in Amperes (A) - Z is the total resistance in the circuit in Ohms (Ω) - t is the time in seconds (s)

In this case, the circuit consists of a battery with an electromotive force (EMF) of 6V and an internal resistance of 0.1Ω, connected to an external circuit with a resistance of 11.9Ω. We need to find the amount of heat generated in the entire circuit over a period of 10 minutes (600 seconds).

To calculate the current flowing through the circuit, we can use Ohm's Law:

I = EMF / (R + r)

Where: - EMF is the electromotive force of the battery in Volts (V) - R is the resistance of the external circuit in Ohms (Ω) - r is the internal resistance of the battery in Ohms (Ω)

Let's calculate the current first:

I = 6V / (11.9Ω + 0.1Ω) = 0.5A

Now, we can substitute the values into the formula for heat:

Q = (0.5A)^2 * (11.9Ω + 0.1Ω) * 600s

Calculating this expression will give us the amount of heat generated in the entire circuit over 10 minutes.

Please note that the search results did not provide the exact values for the resistance and time, so we will use the values provided in the question.
