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.

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.
Calculate the current where 10 coulombs of charge pass a point in 5 seconds?
Current = charge/time = 10/5 = 2 amperes
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.
How much current in amps in in a lightning stroke that lasts 0.05 seconds and transfers 100 coulombs?
Current = Charge / Time = 90 / 0.02 = 4500 Amperes
The filament of an electric lamp draws a current of 0.4 ampere which lights for 3 hours calculate the amount of charge that flows through the circuit?
I=0.4 A T=3hrs=10800 seconDs i=q/t q=It q=0.4*10800 q=4320Coulomb
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.
Calculate the current where 10 coulombs of charge pass a point in 5 seconds?
Current = charge/time = 10/5 = 2 amperes
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.
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.
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.
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).
How much current in amps in in a lightning stroke that lasts 0.05 seconds and transfers 100 coulombs?
Current = Charge / Time = 90 / 0.02 = 4500 Amperes
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
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.
Which type of current capacitor can block and which type of current capacitor can store?
In an electronic circuit a capacitor can be used to block direct current. In general a capacitor stores electric charge. The charge in a capacitor is the voltage times the capacitance and that is also equal to the charging current times the time (all quantities in SI units - seconds, volts, amps, coulombs, farads)
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.
How many coulombs of electricity is generated by a current of 10 amperes running for 2 hours?
No electrical charge is "generated"; the charges are simply moved around. To calculate the amount of charge that flows past a given spot, multiply the current by the time. Don't forget to convert the time to seconds first.
