4 Calculate the current if four coulombs of charge pass a point in a wire every two seconds Show the formula calculations and the units?
(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.
If a charge of 7.4K coulombs flows through a circuit in 85 seconds calculate the current in this circuit?
A flow of 7400 coulombs in 85 seconds represents a current of 87 amperes. One ampere is one coulomb per second, so divide 7400 by 85.
If 10 coulombs of charge passes a specified point in 2 seconds how much current is flowing?
10/2 = 5 coulombs per second = 5 amperes.
Calculate the current where 10 coulombs of charge pass a point in 5 seconds?
Current = charge/time = 10/5 = 2 amperes
What is an example of electric current?
Here are a couple. Assuming everything is "normal" here, if you drop a bagel in the toaster and turn it on by pushing the lever down, the AC current the toaster uses (draws) will stabilize after a few seconds and stay constant. If you turn on your car's headlights, each lamp will draw a constant current from the DC source after a few seconds of "warm up" time. Those are examples of constant electric current.
How much current amperes is in a lightning strike that lasts 0.050 seconds and tar drees 100 Coulombs?
The term "tar drees" does not make sense". Also, 100 Coulombs is awfully small for a lightning strike. Please restate the question.
What is the current in a lamp if 72 coulombs pass through it in 24 seconds?
72 coulombs in 24 seconds is 3 amperes.One ampere is one coulomb per second.

Calculate the charge transferred in 25 minutes by a current of 500 mA?
The charge transferred in 25 minutes by a current of 500 mA is 750 coulombs. Amperes is defined as coulombs per second, so 500 mA is 0.5 coulombs per second. 25 minutes is 1500 seconds, so the charge is 750 coulombs.
How much current is flowing when 16 coulombs pass a specified point in 4 seconds?
If you divide the charge by the time, you get the average current (in amperes).
Calculate the current where 10 coulombs of charge pass a point in 5 seconds?
Current = charge/time = 10/5 = 2 amperes
How long must a current of 2 ampere pass through a 20 ohms resistor until a charge of 1800 coulombs pass through?
Divide the coulombs by the amperes. The answer will be in seconds. The resistance is irrelevant in this problem.
If 5.0 Coulombs of electrons flow past the middle of a copper wire in 0.10 seconds then what is the electric current in that wire?
The current is 50 Amperes, 5/.1=50Coul/sec.
What current Must flow if 0.24 coulombs is to be transferred in 15Ms?
For a steady flow of charge through a surface, the current I in amperes can be calculated with the following equation:I = Q/t where Q is the electric charge transferred through the surface over some time t. If Q and t are measured in coulombs and seconds respectively, I is in amperes. Thus: I = 0.24 coulombs / 15 msec I = 0.24 coulombs / 15 * 10^-3 sec I = 16 amps
How many electrons pass through a conductor in 0.2 second if the current passing through it is 0.5 ampere?
Current = charge / time Charge q = n * e e = 1.602 x 10^-19 C time given = 0.2 s Current = 0.5 A So I = n e / t Hence n = I * t / e Plug I, t and e. You would get required n ANS: 6.24 x 10^17 electrons
