The amount of charge that moves throught the filament of a lightbulb in 2.00 s is 2.67 C. What is the current in the lightbulb?
1.33 A
correct
To calculate the current in the lightbulb, you can use the formula:
Current (I) = Charge (Q) / Time (t)
From the given information, the charge is 2.67 C and the time is 2.00 s.
Plugging the values into the formula:
I = 2.67 C / 2.00 s
I = 1.33 A
Therefore, the current in the lightbulb is 1.33 A.
