Question 10 10 pts A battery is used in a physics lab to supply current to a circuit. A voltmeter connected in parallel across the cell reads 5.86 V in an open circuit (figure a) and 5.83 V in a closed circuit (figure 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.Question 4 10 pts Find the total resistance (in Ohms) for the circuit in the gure given that: R1 = SQ, R2 = 7 Q and R3 = 12 Q. Your answer should be a number with one decimal place, do not include the unit. R ' A Determine the current through R1 (in Amperes) for the circuit in the gure given that: R1 = 3 Q, R2 = 5 Q, R3 =14QandV=21 V. Your answer should be a number with two decimal places, do not include the unit. R ' A
