What happens to the current at a junction in a parallel circuit?

In a parallel circuit the current divides when it comes to a junction. Part of the current flows through one branch and the other part flows through the other.
When the two branches have the same resistance, the same current flows through each branch.
When the two branches have different resistances, a bigger current flows through the branch with the smaller resistance - it's just easier this way!
Hope i helped ;)

What happens when one light bulb goes out in a series?
The failed bulb breaks the circuit so no current can flow - so the other bulb goes out (but is OK).
What happens if there is a short circuit in a parallel circuit?
Incorrect answerThen only one of the lights go out.Correct answerActually ALL the lamps will go out if a short circuit occurs across any branch of a parallel circuit because, if the wiring has been done correctly, a circuit breaker will trip or a fuse will blow to cut off the supply of current to all the lights.The loss of a single lamp indicates a break, not a short circuit.
What happens in parallel circuit if one load is broken or missing?
it won't flow
What happens to the current when more resistors are added in series?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
What happens to other lamps in a parallel circuit if one lamp burns out?
If one lamp in a parallel circuit burns out, the other lamps are unaffected because current still flows through them. Total current in the system is reduced by the loss of the burned out lamp, which will raise voltage ever so slightly. That will have the effect of brightening the other lamps, but that effect is inconsequential unless there is significant impedance in the source or in the path to the lamps.
What happens to the current in the series circuit?
current remains same in series while divide itself in parallel circuit
what happens to current in a circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What happens to current in a parallel circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
What happens to the total current provided by the battery as more bulbs are added to a parallel circuit?
The total current increases in this case.
What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
What happens if a light blows in a parallel circuit?
The rest of the lights in the system will remain illuminated. Except in that branch of the circuit. The parallel branch(s) get more current if the voltage potential remains the same.
What happens to voltage and current in a parallel circuit?
-- The voltage between the ends of each parallel branch is the same. -- The current through each parallel branch is inversely proportional to the resistance of that branch. (It's the voltage divided by the resistance of the branch.)
What happens if there is a break in a serious circuit?
A break in an electrical circuit will cause the circuit's load to stop operating.
Why a circuit will produce a loading effect?
This happens because the total parallel resistance is lower than the individual resistors that make up the group of parallel resistors. When you add another parallel load, the resistance of that parallel group lowers and as result increases the current for the rest of the circuit.
