By Kirchoff's current law, the sum of the signed currents entering a node is zero.
In a parallel circuit, this means the sum of the (often single) current(s) entering a node (junction) is the same as the sum of the (two or more) currents leaving that node.
To determine the current in a particular branch, you need the voltage and resistance, or you need something else that you can use to calculate the current.
In the second case, if you know the total current and one branch current in a two branch circuit, you know the other branch by calculating total minus first branch.
For the first case, one method is to take advantage of Kirchoff's voltage law, which states that the signed sums of the voltage drops around a series circuit is zero. In a parallel circuit, this means that the voltage drop across each branch is the same. If you then also know resistance, you know current.
What else can I help you with?
The current in a what circuit is the same at every point?
A series circuit has the same amount of current at all points in the circuit.CommentIt's not simply 'the same amount of current at all points''; it's the same current at all points.
What is the current of a series-parallel circuit connection?
The current flowing through a series circuit is (voltage between the circuit's ends) / (sum of all resistances in the circuit). The current is the same at every point in the series circuit.
What electrical quantity is the same throughout a series circuit?
In any series circuit, there is one and only one path for current flow. All the current flowing in the circuit will flow through all of the devices in that circuit. A break at any point in the circuit will cause current flow to cease. Lastly, it is current that is the same at any point in the circuit where we'd care to measure it.
In a series circuit what would happen if one of the bulbs stopped working?
All the bulbs will go out. In a series circuit, the current at all points is the same. This is Kirchoff's Current Law. If you loosen or remove a bulb in a series circuit, the current at that bulb becomes zero, and by Kirchoff's Current Law, the current in every part of the circuit also becomes zero.
How is current distributed in a series circuit?
In a series circuit, all components gets the same amount of current passing through them.
The current in a what circuit is the same at every point?
A series circuit has the same amount of current at all points in the circuit.CommentIt's not simply 'the same amount of current at all points''; it's the same current at all points.
Is the voltage the same throughout all points in a series circuit?
Yes, in a series circuit, the voltage is the same at all points because there is only one path for the current to flow, so the total voltage is divided across all components in the circuit.
What is the current of a series-parallel circuit connection?
The current flowing through a series circuit is (voltage between the circuit's ends) / (sum of all resistances in the circuit). The current is the same at every point in the series circuit.
The parts of a series circuit are wired one after another so the amount of curren is the?
There is no current at all in the series circuit until the last component is in place, and the order in which they're arranged in the series circuit has no effect on the magnitude of current.
Voltage varies or is the same in all parts of a series circuit?
Current is the same at all points in a series circuit.No statement can be made concerning voltage. Voltage is a potential differencebetween two points, and you haven't specified a point for reference.
How does current travel in a series circuit?
Current in a series circuit travels in one path. This is because a series circuit is only one path. current in a series circuit stays the same thoughout the circuit this means that if in the beginning of the circuit there are 2 amps of current there will be the same ammount of current in the middle and in the end of it. if you don't understand this please tell me and ill explain in a better way.
What is the same in all parts of a series circuit?
Current.
What electrical quantity is the same throughout a series circuit?
In any series circuit, there is one and only one path for current flow. All the current flowing in the circuit will flow through all of the devices in that circuit. A break at any point in the circuit will cause current flow to cease. Lastly, it is current that is the same at any point in the circuit where we'd care to measure it.
Is voltage the same at all points in a circuit?
Yes it is in series and parallel
In a series circuit what would happen if one of the bulbs stopped working?
All the bulbs will go out. In a series circuit, the current at all points is the same. This is Kirchoff's Current Law. If you loosen or remove a bulb in a series circuit, the current at that bulb becomes zero, and by Kirchoff's Current Law, the current in every part of the circuit also becomes zero.
In a series circuit what is the same at every point?
Current. There is only one path that current can take through the circuit, so the current must be the same at every point.
How is current distributed in a series circuit?
In a series circuit, all components gets the same amount of current passing through them.
