Dear Sir/Madam,
I read both https://www.allaboutcircuits.com/textbook/direct-current/chpt-11/battery-ratings/ and https://www.allaboutcircuits.com/textbook/direct-current/chpt-2/calculating-electric-power/ but cannot answer my question.
Many STEM users connect an MCU like Microbit with a motor, even though it can provide 3.3V to the motor, the motor cannot be started up because of the limited output current. It explains only voltage be considered, the current is also the factor.
I want to make a box that can produce different voltage output for daily testing use, I want to have a 4x1.5V battery cell as input voltage and then use a DC-DC Step-up to meet my need when test. How can I know the maximum current of the battery cell can produce? How can I measure it?
Best regards,
Kelvin.
