A battery is used in a physics lab to supply \( 3.00 \mathrm{~A} \) to a circuit. A voltmeter connected in parallel across the cell reads \( 6 \mathrm{~V} \) in an open circuit (figure a) and \( 4.7 \mathrm{~V} \) in a closed circuit (figure b) when the cell supplies \( 3.00 \mathrm{~A} \) to the circuit. What is the internal resistance of this battery (in Ohms)? Your answer should be a number with three decimal places, do not include the unit. A battery is used in a physics lab to supply current to a circuit. A voltmeter connected in parallel across the cell reads \( 5.02 \mathrm{~V} \) in an open circuit (figure a) and \( 4.83 \mathrm{~V} \) in a closed circuit (figure b) when the cell supplies \( 2.5 \mathrm{~A} \) to the circuit. How much electrical power does the cell produce (in Watts)? Your answer should be a number with three decimal places, do not include the unit.
