A steady current of 0.50 A flows through a wire. (a) How many coulombs of charge pass through the wire per second? (b) How many per minute?
A charge of 1020 C wss passed through a wire in 5.50 minute. What was the average electric current during that time?
A charge of 833 C was passed through a wire in 1.00 minute. What was the average electric current during that time?
an ampere is a coulomb per second ... charge / time
To find the number of coulombs of charge passing through the wire per second and per minute, we can use the formula:
Charge (Q) = Current (I) * Time (t)
Given:
Current (I) = 0.50 A (Amperes)
(a) To find the charge passing through the wire per second, we need to consider the time (t) as 1 second.
Therefore, using the formula:
Q = I * t
Q = 0.50 A * 1 second
Q = 0.50 Coulombs
Therefore, 0.50 Coulombs of charge pass through the wire per second.
(b) To find the charge passing through the wire per minute, we need to consider the time (t) as 1 minute.
However, we need to convert the time from minutes to seconds since the current is given in Amperes (per second).
1 minute = 60 seconds
Therefore, using the formula:
Q = I * t
Q = 0.50 A * 60 seconds
Q = 30 Coulombs
Therefore, 30 Coulombs of charge pass through the wire per minute.
