Current flow through a lamp is 1.3 A. How many Coulombs of charge are passed through the lamp in 2 minutes?
Formula for coulombs and current? Not sure..
Charge in Coulombs = (Current in Amperes)x(Time in seconds)
Q = I*t = 1.3*120 = 156 C
To calculate the number of Coulombs of charge passed through a device, you can use the formula:
Q = I × t
where
Q = charge in Coulombs
I = current in Amperes
t = time in seconds
In this case, we have the current (I) as 1.3 A and we need to find the charge in Coulombs for a time of 2 minutes. However, the formula requires the time to be in seconds, so we need to convert 2 minutes to seconds.
1 minute = 60 seconds
Therefore, 2 minutes = 2 × 60 = 120 seconds.
Now we can plug in the values into the formula:
Q = 1.3 A × 120 s
Q = 156 Coulombs
Therefore, the charge passed through the lamp in 2 minutes is 156 Coulombs.
The formula to calculate the amount of charge (in coulombs) passed through a circuit is:
Q = I * t
Where Q is the charge, I is the current (in amperes), and t is the time (in seconds).
In this case, the current flowing through the lamp is 1.3 A, and the time is 2 minutes. However, the formula requires time to be in seconds. So, first, we need to convert 2 minutes to seconds.
1 minute = 60 seconds
Therefore, 2 minutes = 2 * 60 = 120 seconds.
Now, we can substitute the values into the formula:
Q = 1.3 A * 120 s
Calculating the product:
Q = 156 Coulombs
Therefore, 156 Coulombs of charge are passed through the lamp in 2 minutes.
