    Determine the maximum current discharged from a battery

    You're right, it should be the chemistry of the battery that limits the current. Was trying to understand how to calculate such a current, trying too hard I guess.. The main thing I've learned is not to apply ohm's law blindly, as ohmic resistors can become non-ohmic subjected to high...

    Determine the maximum current discharged from a battery

    he was referring to this battery: " a typical small 9V battery (2010) " and telling us we would not get 900A if we were to short it

    Determine the maximum current discharged from a battery

    Sorry if I weren't making good sense here..I'm a freshman currently doing my 1st electrical engineering course. Because I learned that ohm's law is only an approximation, in fact variation of current with voltage across an element is not always linear. Also the other day my prof was saying...

    Determine the maximum current discharged from a battery

    Hi, I'm not sure about how manufacturers calculate the maximum constant current that a battery can discharge. I understand that a battery capacity rating is given by 20hrs multiplied by the maximum current value. I learned also that by shorting a 9V battery of internal resistance 0.01ohms, we...
