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?
Based on what you have seen what must be true for a circuit to light a bulb?
There must be a current through the bulb in order for it to glow.
If a parallel circuit shorts at the battery will the entire circuit short out too?
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

An electric dc circuit is attached to a 12 volt battery and has a 3ohm resistor in it What is the current flowing through the circuit?
The current depends on the total effecvtive resistance of everything connectedacross the battery.If the resistor is the only component there, then the current is E/R = 12/3 = 4 amperes.
What kind of circuit allows a current to flow through?
Any complete circuit. ==== An electrical circuit.
Why does a circuit stop working when you remove the battery?
The battery is the power source of the circuit. It supplies current to the circuit and the circuit is simply a path for the current to follow. When you remove the current (battery), the path still exists but there is no current going through it.
What is current in the battery called?
A battery contains a charge of electrons. When these electrons leave the battery and travel through a circuit that is described as current.
Should you connect both ends of a battery in a circuit?
it is necessary to connect both the terminals of a battery to a circuit for current to flow through it..!!
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
What causes a posite current in a battery?
A electrical from a battery is the flow of elecrons through a circuit in the opposite dirrection to the current flow. This current flow also happens inside the battery between the plates.
What is an complete circuit?
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
How does an electric circuit with a battery lamp copper wire and switch work?
The battery provides the current and the energy; the lamp consumes the energy when the current goes through it; the copper wire conducts the current; and the switch lets you close or open the circuit (so that current passes, or doesn't pass, through).
A 9v battery is in a series with a 100 resistor and there is a current of 0.09 a flowing through the circuit what is used by the circuit?
0.81 APEX
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 happens when a battery is hooked up to an open circuit?
nothings because they is no wire connected to the circuit so no current can flow through
In an electric current electricity flow how?
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that have their own wire.ClarificationThe above answer, unfortunately, perpetuates the myth that current leaves a battery, and finds its way around a circuit. This is not the case at all. It is the load that 'draws' the current from the battery and it is the load that determines the size of that current.
