It is corret:

R1*I1 + R2 * I2 + E2 + E1 = 0
0,01I1 + I2 -10 +12 = 0
I2 = -0,01I1 -2


R3*I1 = E2 + R2*I2
0,06I1 = -10 + I2
I2 = 0,06I1 + 10


0,06I1 + 10 = -0,01I1 - 2
0,07I1 = -12
I1 = -171,42 A

I2 = -0,2858A


I1 => current at start-up
I2 => current battery discharged

Correct ?

What's your justification for assuming that the current through R3 is the same as that through R1?
 

What is the purpose of determining the current at start-up and the battery discharged?

Determining the current at start-up and the battery discharged is important for understanding the behavior and performance of a battery. It helps to determine the amount of current that is drawn from the battery during start-up and the amount of energy that has been discharged from the battery over time.

How is the current at start-up and the battery discharged measured?

The current at start-up and the battery discharged are typically measured using a multimeter. The multimeter is connected in series with the battery and measures the flow of current through the circuit. The readings can then be recorded and analyzed to determine the current and discharge of the battery.

What factors can affect the current at start-up and the battery discharged?

The current at start-up and the battery discharged can be affected by various factors such as the internal resistance of the battery, the load connected to the battery, the temperature, and the age of the battery. These factors can impact the performance and lifespan of the battery.

Why is it important to determine the current at start-up and the battery discharged?

Determining the current at start-up and the battery discharged is crucial for assessing the health and efficiency of a battery. It allows for early detection of potential issues and helps to optimize the performance and usage of the battery. It also provides valuable information for designing and improving battery systems.

What are some potential applications for determining the current at start-up and the battery discharged?

The measurement of current at start-up and the battery discharged is useful in a variety of applications such as electric vehicles, renewable energy systems, mobile devices, and other electronic devices. It is also important in research and development of new battery technologies and in maintaining the safety and reliability of battery-powered devices.
