A non-ideal 12.2 V battery is connected across a resistor R. The internal resistance of the battery is 1.9Ohm. Calculate the potential difference across the resistor for the following values. R = 100 Ohm Express the potential difference in volts to two significant figures. R = 10 Ohm Express the potential difference in volts to two significant figures. R = 2 Ohm Express the potential difference in volts to two significant figures. Find the current through me battery for R = 100 Ohm Express your answer in amperes to two significant figures. Find the current through me battery for R = 10 Ohm Express your answer in amperes to two significant figures.
