Question:

You have a battery marked \"6.00 V.\" When you draw a current of 0.225 A from it, the potential difference between its terminals is 5.09 V. What is the potential difference when you draw 0.487 A? THIS IS THE WHOLE QUESTION SOMEONE PLEASE HELP


Answers

Calula voltage is lost, for internal resistance of the battery

V_{lost}=V_{battery}- V_{measured}=6V-5.09V=1.18V

Applying Ohm's law to calculate the value of the resistance

R=V_{lost}/I=0.91V/0.225V=4.04\Omega

Ohm's law is again applied to calculate the difference of potential loss

For I=0.487A

V_{lost}=I\cdot R=0.487A\cdot 4.04\Omega =1.97V

the potenial difference between its terminals will be equal to

V_{measured}=V_{battery}-V_{lost} =6V-1.97V=4.03V
