Q5.	Convert 0.15 milliampere (0.15 mA) to microamperes (µA).
A.	130 µA [Wrong Answer]
B.	140 µA [Wrong Answer]
C.	150 µA [Correct Answer]
D.	160 µA [Wrong Answer]
View Answer 2 -1 Explanation:- Answer : C Discuss it below : Move the decimal point three places to the right. 0.15 mA = 0.15 X 10^-3 A = 150 X 10^-6 A = 150 µA Or First convert mA into A as 0.15 mA = 150 A Then convert it into in micro ampere Click here for more comments
