If the 12.0-V battery in his car is rated at 41.0 A h and each headlight requires 40.2 W of power, how long will it take the battery to completely discharge? 6.1194 hours 3. +414 points | Previous Answers My Notes 7:22 PM 2/11/2016 Search the web and WindowsExplanation / Answer
First we find the equivalent resistance of circuit.
10 ohm and 5 ohm are in parralle.so
equivalent resistance of 10 ohm and 5 ohm = 5*10/(5+10) = 3.33 ohm
now equivalent resistance of 3.33ohm and R2 = 3.33 + 10 = 13.33 ohm
equivalent resistance of 13.33ohm and R1 = 13.33*5/(5+13.33) = 3.63 ohm
equivalent resistance of circuit = 3.63 + 2 = 5.63 ohm
current in circuit = V/Req = 9/5.63 = 1.6 A
now current through R1 = 1.6*13.33/(5+13.33) = 1.16 A
voltage across R1 = I*R = 1.16*5 = 5.8 volt
