This happens only in pure series circuits, due to increased resistance.

Does the current remains the same in a series circuit despite the different values if the resistors in the circuit?
current in series depends on values of resistors. more resistance less current will flow through and viceversa
What is the current running through a 90 volt circuit?
It depends on the resistance of everything connected between the terminals of the power supply. If the resistance is infinite or very high, there is little or no current. As the resistance becomes less, the current becomes greater. In general, the current through a circuit with 90 volts applied to it is [ 90 / R ], where 'R' is the resistance of everything across the 90-volt power supply.
Is the total resistance of all the parallel loads more than the smallest individual resistance?
No. Perhaps an analogy would help understand the answer to this question. When you are at the store, and you are in a line waiting to be paid, opening up another line or more should increase how fast people can move through the store. That is a parallel operation. (If you have to go through one line at the store and then go through another line at the store, that is a series operation). Similarly, when a current meets a resistance, putting additional resistance in PARALLEL allows some of the current to divert to this new path or paths, allowing more current to flow through the combination of resistances. Since more current is flowing though the combined resistances, the equivalent resistance is less since less resistance always means more flow.
Is the current in one branch of a parallel circuit more than less than or equal to the total current entering the junction point of the circuit?
Answer: less. Answer: Kirchhoff's Current Law states that the sum of all currents into a junction (or out of a junction) must be zero. This refers to the algebraic some, that is, if you consider the current into the junction, any current entering the junction will be counted as positive, while any current leaving the junction will be counted as negative. Thus, any individual current will be equal to the negative of the sum of all the other branches at the junction.
Why lpf wattmeter used in no load?
Basically at noloads the current value is less so we use lpf at no loads
What happens to the voltage in a series circuit when more loads are added?
A: assuming a infinite current source the current will increase accordingly
What determines the current in each branch of a parallel circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.
What determines the current in each branch of parallel of circuit?
The resistance of the component on that branch of the circuit, if the resistance is higher less of a proportion of the total current of the circuit will travel through that branch, however, if the resistance is low a higher proportion of the current will travel through that branch of the circuit. The voltage through each branch stays the same.

Why is a current in a circuit never used up?
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.
Why might the current in a short circuit be higher than the current in the original circuit?
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
Is the current in one branch of a parallel circuit more than less than or equal to the total current?
its less then the total current
What is a parralell curcuit?
• In a parallel circuit, there are junctions in the circuit so the current can flow around the circuit in more than one way. • In a series circuit the current decreases as more bulbs are added. •In a parallel circuit, as more bulbs are added, the current increases. • This is because bulbs added in parallel offer less resistance
Are no load and short circuit similar?
No. No load and short circuit is not similar. No load can be 1) Either open circuit i.e. Only Potential is available and load is not connected 2) Load (i.e. motor etc ) is connected but not working with full load or full capacity. In this case the current will flow through the circuit depending on the load. It means No load condition is a condition where no current or a small ( relative / comparative term) current is flowing through the circuit. In Short circuit the load side resistance/ impedance become so less that very high amount of current is passing through circuit.( The protection is therefor required for any circuit) No load and and short circuit is not similar. Thanks
In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?
By adding more light bulbs
