Question
A battery having an emf of 9.00 $V$ delivers 117 $\mathrm{mA}$ when connected to a $72.0-\Omega$ load. Determine the internal resistance of the battery.
Step 1
We know that 1 ampere is equal to 1000 milliamperes. So, we have: $$ I = 117 \, \text{mA} = 0.117 \, \text{A} $$ Show more…

A battery having an emf of $9.00 \mathrm{~V}$ delivers $117 \mathrm{~mA}$ when connected to a $72.0-\Omega$ load. Determine the internal resis- tance of the battery.
A battery produces $15.5 \mathrm{~mA}$ when it's connected to a $230-\Omega$ load and $22.2 \mathrm{~mA}$ when it's connected to a $160-\Omega$ load. Find the battery's emf and internal resistance.
A $1.40-\Omega$ resistor is connected across a $9.00-\mathrm{V}$ battery. The voltage between the terminals of the battery is observed to be only 8.30 $\mathrm{V}$ . Find the internal resistance of the battery.
