To calculate the current that an ammeter will register if 960C of charge flow through it in 2 minutes, we can use the formula:

$$i = \frac{q}{t}$$

where i is the current, q is the charge, and t is the time. Substituting the given values, we get:

$$i = \frac{960C}{2min} = 480C/min$$

Therefore, the current that an ammeter will register is 480C/min.
