What is the result of 0.3ma x 8 seconds?

To determine the result of 0.3 mA multiplied by 8 seconds, it's important to understand the relationship between milliamperes (mA), seconds, and units of electrical charge, which are typically expressed in microcoulombs (µC).

In this context, 1 mA (milliampere) is equal to 1/1000 of an ampere. When multiplying milliamperes by time in seconds, the product gives you a measure of charge. The formula for electrical charge (Q) is:

Q (in coulombs) = Current (in amperes) x Time (in seconds).

Since we need to convert to microcoulombs, we can apply the following conversions:

1 mA = 0.001 A,

1 coulomb = 1,000,000 microcoulombs (µC),

Now applying this to the calculation:

0.3 mA = 0.3 x 0.001 A = 0.0003 A.

Now multiply this current by the time:

Q = 0.0003 A x 8 s = 0.0024 C.

To convert coulombs to microcoulombs:

0.0024 C
