What is the current (in amperes) if 0.71 coulomb of charge passes by a point every 8.9 ms?Select one:a.7.97 Ampsb.79.7 Ampsc.797.7 Ampsd.0.797 Amps
Solution
The current (I) in a circuit is defined as the amount of charge (Q) passing through a point in a given time (t). This is given by the formula:
I = Q/t
Given that Q = 0.71 coulombs and t = 8.9 ms, we can substitute these values into the formula. However, we need to convert the time from milliseconds to seconds because the standard unit of time in this context is seconds.
1 ms = 0.001 s, so 8.9 ms = 8.9 * 0.001 = 0.0089 s.
Substituting these values into the formula gives:
I = 0.71/0.0089
Calculating this gives:
I ≈ 79.78 Amps
So, the closest answer is b. 79.7 Amps.
