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.
How many coulombs of charge flows through an electric circuit through which a current of 250 M ampere flows for 30 minutes?
250 mA = 0.25 Ampere = 0.25 coulomb per second.(0.25 coulomb/second) x (60 sec/minute) x (30 minutes) = 450 coulombs
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.
What is the units of electric current?
The unit quantity of electricity is the Coulomb. The rate of electricity flow in coulombs per second is the Ampere, sometimes shortened to Amp. Note: current doesn't flow, instead current itself is a flow rate (flow of coulombs of charge per second.) When coulombs are flowing, the flow rate is measured in amperes.
What is the current across a 10k resistor and 20 volts?
First of all, current goes straight through the resistor, not across it.If the potential difference between the ends of the resistor is 20 volts,and its resistance is 10,000 ohms, then the current through it isI = E/R = 20/10,000 = 0.002 ampere = 2 milliamperes
Which is true resistor?
hinders flow of current
What is the current in circuit with 6 v battery and 2 resistor?
3 ampere
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.
If two bulbs in a series are connect to a battery and the current in the first bulb is found to be 1 ampere then what is the current through the battery?
A circuit with a 2 ohm resistor and a 4 ohm resistor in series with a 12 volt battery will have 2 amps flowing through each resistor. The current is the same in each resistor because they are in series, and a series circuit has constant current throughout.
If a battery sends a current of 10 amps through a circuit for one hour how many coulombs will flow through the circuit?
If a battery sends a current of 10A through a circuit for one hour how many coulombs will flow through the circuit?
What is the unit of electron current?
Electron current flow is measured in coulombs per second, which is known as amperes. A coulomb is about 6.242 × 1018 electrons.
What is the unit of electricity current flow?
The unit quantity of electricity is the Coulomb. The rate of electricity flow in coulombs per second is the Ampere, sometimes shortened to Amp. Note: current doesn't flow, instead current itself is a flow rate (flow of coulombs of charge per second.) When coulombs are flowing, the flow rate is measured in amperes.
