Three resistors, 12.2 ?, 50.9 ?, andR, are connected in series with a 15.0 V battery. The total current flowing through the battery is 0.125 A.
Calculate the value of resistanceR.
Calculate the potential difference across the 12.2 ? resistor.
Calculate the potential difference across the 50.9 ? resistor.
Calculate the potential difference across R.
If the voltage of the battery had been greater than 15.0 V, would the value of resistance R have been larger or smaller?
