If the current in a wire of a CD player is 5.00 mA, how long would it take for 2.00 C of charge to pass through a cross-sectional area of this wire?
monkey
I=Q/t
T= Q/I => 2.00/5.00= 0.4s
one ampere is one Coulomb of charge per second
time = charge / current
Cu = I * T
T = Cu / I = 2 / 5 * 10^{3}
Time = 400 seconds
To find the time it takes for a specific amount of charge to pass through a wire, we can use the formula:
time = charge / current
In this case, the charge is given as 2.00 C and the current is given as 5.00 mA. However, we need to convert the current to amperes (A) because the charge is in coulombs (C).
1 ampere (A) = 1000 milliamperes (mA)
So, the current is 5.00 mA = 5.00 * 10^(-3) A.
Now, we can substitute the values into the formula:
time = 2.00 C / (5.00 * 10^(-3) A)
Calculating this, we get:
time ≈ 400 seconds
Therefore, it would take approximately 400 seconds for 2.00 C of charge to pass through the wire.
Cu = I * T.
T = Cu/I = 2/5*10^-3 = ----seconds.
t =
