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
An electric bulb draws a current of 0.25A for 20 minutes calculate the electric charge?
1 Ampere = 1 Coulomb per second0.25 A = 0.25 Coulomb per sec1 minute = 60 seconds20 minutes = (20 x 60) = 1,200 seconds0.25 A for 20 minutes = (0.25 x 1,200) = 300 Amp-seconds = 300 Coulombs of charge
How much current exists if 225 coulombs pass a poinjt in 5 seconds?
1 Ampere = 1 Coulomb/sec (225 Coulomb) / (5 sec) = 45 Coulomb/sec = 45 Amp.
How long does it take 9 coulombs to pass a current of 3 amps?
1 Amp = 1 Coulomb/sec 3 Amps = 3 Coulomb/sec Time = (9 coul) / (3 coul/sec) = 3 seconds
How much enegry is available from a 12v storage battery that can transfer a total charge equivalent to 100000C?
The battery can move a charge of 100,000 coulombs through a potential difference of 12 volts, therefore the energy released is 12 x 100,000 coulombs, or 1.2 Megajoules. 100,000 coulombs is (for example) 10 Amps for 10,000 seconds, in other words 10 amps for 2.78 hours, so its capacity is 27.8 ampere-hours.
What is a current electricity?
An electric current is the amount of electrons per unit time or seconds.
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.
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.
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
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.
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
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
An electric bulb draws a current of 0.25A for 20 minutes calculate the electric charge?
1 Ampere = 1 Coulomb per second0.25 A = 0.25 Coulomb per sec1 minute = 60 seconds20 minutes = (20 x 60) = 1,200 seconds0.25 A for 20 minutes = (0.25 x 1,200) = 300 Amp-seconds = 300 Coulombs of charge
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
