A battery is used in a physics lab to supply current to a circuit. A voltmeter connected in parallel across the cell reads 5.17 V in an open circuit (figure a) and 4.83 V in a closed circuit (figure b) when the cell supplies 2.1 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. Figure a Figure b
