Kirchoff's Current Law: The signed sum of the currents entering a node is always zero. A consequence of this is that, for series circuits, the current at every point in the circuit is the same.
If this does not answer the intended question, please restate the question and provide more information as to what, exactly, you are looking for. "Used up" is a vague and non-scientific term that does not entirely make sense.
AnswerElectric current is not 'poured' into a circuit, like water from a kettle. Current is 'drawn' from the voltage supply by the load. It is a load that determines how much current is drawn for any given supply voltage. 'Heavier' loads (i.e. lower resistance loads) draw larger currents, while 'lower' loads (i.e. higher resistance loads) draw less current.

What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
What is the strength of current in each resistor of a series circuit?
The current in each resistor in a series circuit is the same. Kirchoff's Current Law states that the sum of the currents entering a node must add up to zero. The connection between two resistors in a series circuit is a node. The current entering the node from one resistor is equal to the current leaving the node into the next resistor.
If resistance goes up does current go down?
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
What is a connection that allows current to take the path of least resistant?
Current will tend to take the path of least resistance in any case. That's its nature. A short circuit (or "short") is a low resistance current path that current will follow if it appears.
How does read-out integrated circuit works?
Read out integrated circuit refers to integrated circuit specifically used for reading detectors of a particular type. These are used in detectors where the sensitivity is very low and using a discrete circuit may not be useful as noise may be large enough to cover up whole signal.
What is use of capacitor in electronics circuit?
to limit the current and to use it as a back up battery capacitors are used ..
What type of device is used to decrease or increase the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.

In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What type of device is used to increase to decrease the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What are the 2 rules for the voltage and current in a series circuit?
In a series circuit, the current remains constant throughout the circuit. The voltage across each component in a series circuit adds up to the total voltage of the circuit.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
What is a hypothesis stating how a fuse is used to prevent too much electric current from flowing through a circuit?
This would not be a hypothesis, but an explanation. A fuse is a piece of wire with a low melting point which melts if too much current flows in the circuit. It is designed to break before the rest of the circuit is damaged.
How are watts used in real life?
A watt is a measure of electrical power. If you want to know how much current a circuit will draw, and you have wattage ratings of appliances or devices then you can calculate the current. {Power = Voltage × Current}. On a 110 Volt circuit, you can add up the wattages and then divide by 110 volts, to get current in amperes.
What si th difference between a series and parallel circuit?
The primary difference between a series and a parallel circuit is how many pathways the current has to travel in. Let's look at both of them and see what's up. In a simple series circuit, there is only one path for current. The current must flow through every component in the circuit.
Why is the fuse always connected in the beginning of the circuit?
A fuse is an over current protection device, and will operate wherever it is placed in a circuit. However, because it's important that it isolates the faulty circuit from the supply, it MUST be located in the line (NEVER the neutral) conductor at the point where the circuit is connected to the supply.The point is that the circuit will always be energised (and potentially dangerous) up to the point where the fuse is connected, even when the fuse has operated and no current can flow.
Why does an electrical breaker trip when you use a lot of appliances in the house?
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
