The series circuit shown is built using an 30-bolt battery (V=30V) and three bulbs having R1=4, R2=6 and R3=5

47. Calculate the total resistance of the bulbs. 2 points OR = 40 R = 50 OR= 60 O R = 120 O R = 150 48. How much current flows when the switch is closed? * 2 points OAI = 1A O B) I = 2A O Q) I = 3A O D) I = 6A O E I =9A OF) I = 18A 49. What is the voltage Vz across the middle (R2 = 602) bulb? * 2 points A) V2 = OV B) V2 = 1V O C) V2 = 3V ( D) V2 = 6V O E) V2 = 9V OF) V2 = 12V
