Two resistors R_1 = 300 Ohms and R_2 = 200 Ohms are in parallel connected to a 1

Question

Two resistors R_1 = 300 Ohms and R_2 = 200 Ohms are in parallel connected to a 12 volt battery. Which resistor is using more power? A) R_1 B) R_2 C) They use the same power since they have the same current flowing through them D) Can't tell from this info A 60 W bulb (240 Ohms) and a 75 W (192 Ohms) bulb are in series connected to a 120 volt wall socket. Which bulb will be brighter? A) 60 W B) 75 W C) They use the same power since they have the same current flowing through them D) Can't tell from this info

Explanation / Answer

Q.8

power across R1= 12^2/ 300 = 0.48 W

power across R2= 12^2/200= 0.72 W

correct option is B

Q.9 60 Watts ( high resisatnce)
