A charge of 10 coulombs has been travelling through the wire of a simple circuit,with a current of 3 A. How long has the current been flowing?
To find out how long the current has been flowing, you can use the relationship between charge (Q), current (I), and time (t), which is given by the equation:
Q = I * t
In this case, you are given the charge (Q) as 10 coulombs and the current (I) as 3 amperes. You need to find the time (t) in seconds.
Rearranging the equation, we have:
t = Q / I
Substituting the given values, we can calculate the time:
t = 10 C / 3 A
Now, divide 10 Coulombs by 3 Amperes to find the time:
t = 3.33 seconds
Therefore, the current has been flowing for approximately 3.33 seconds.
