Because of the internal resistance of a real battery, we know that the potential difference between the terminals: a. decreases as more current is drawn.
b. increases as more current is drawn.
c. is greater than the emf of the battery
d. increases as the internal resistance increases.

I think the ans is A but I’m not sure.

Can someone check it and tell me I would like to know

in physics zero. in muscle fatigue could be high

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
