A 10-ohm resistor has a constant current.If 1200 C of charge flow through it in 4 minutes what is the value of the current?
A)3.0 A
B)5.0 A
C)20 A
D)120 A
E)300 A

Question

We can use the formula:

current = charge/time

In this case, the charge is given as 1200 C and the time is given as 4 minutes, or 240 seconds.

So,

current = 1200 C / 240 s = 5.0 A

Therefore, the answer is B.

A 10-Ohm Resistor Has a Constant Current
