Question 9 A battery is used in a physics lab to supply current to a circuit. A voltmeter connected in parallel across the cell reads 5.56 V in an open circuit (gure a) and 4.83 V in a closed circuit (gure b) when the cell supplies 2.9 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.

A voltmeter connected in parallel across the cell reads 5.86 V in an open circuit (gure a) and 5.89 V in a closed circuit (gure b) when the cell supplies 2.2 A to the circuit. What power goes to its load (in Watts)? Your answer should be a number with three decimal places, do not include the unit
