What is the current through a wire if 240 coulombs of
charge pass through the wire in 2.0 minutes?
240coul/2.0min * 1min/60s = 2.0coul/s = 2.0A
2.0 A
To calculate the current through a wire, you need to use the formula:
Current (I) = Charge (Q) / Time (t)
Given that 240 coulombs of charge pass through the wire in 2.0 minutes, we can substitute these values into the formula:
I = 240 C / 2.0 min
However, it is important to note that current is typically measured in amperes (A), and minutes is not the standard unit of time in the International System of Units (SI). We need to convert minutes into seconds, since the SI unit for time is seconds.
1 minute = 60 seconds
So, 2.0 minutes = 2.0 min * 60 s/min = 120 seconds
Now we can substitute the values into the formula:
I = 240 C / 120 s
Simplifying the calculation:
I = 2 A
Therefore, the current through the wire is 2 amperes (A).
Current= change in charge / time
Charge = 240 coulombs
time= 2 minutes
convert minutes to seconds so time = 120 seconds
240 c/ 120 s= 0.5 A
