Answer to Question #189710 in Physics for Ysabella Bazan

Question

An ammeter measures a current of 4 A In a time interval of 2.0s . Determine the amount of charge that passed through the ammeter during this time

Answer 1

By definition, the current is:

$$I = \dfrac{q}{t}$$

where $q$ is the charge that passed in time $t = 2s$. Since $I = 4A$, obtain:

$$q = It\\ q = 4A\cdot 2s = 8.0C$$

Answer. 8.0C.
