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 formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is Kirchoff's current law in electronics engineering?
Kichoff's current law says that the signed sum of the currents entering a node is zero.So, if you have a node with two wires, then the current on the first wire will exactly match the current on the other wire. If you have a node with three wires, then the currents will match up - lets say you had +2 amps on one wire and +3 on the second - the the third must be -5. (+n means current entering, -n means current leaving, that's why he said signed sum.An important consequence of this law is that, in a series circuit, the current at every point along that circuit is the same.
What is a rule for current flowing round a circuit?
In a series circuit, the current at every point in the circuit is the same. This is a consequence of Kirchoff's Current Law, which states that the signed sum of the currents entering a node must equal zero. Since a series circuit consists of nodes with only two elements connected to each node, it follows that the current at every point in a series circuit is the same.
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.
Explain Why it is important that the current in the coil of a motor changes direction every time the coil makes a half revulotion?
due to commutation the current in the coil reverses
Is the Earth's tilt and revolution the reason for the changes in the Earth's climate every year?
The earth's tilt and revolution around the sun are responsible for the changes in the seasons, from spring through to winter, every year.
What is an example of conflict producing changes?
Every war or revolution in history has produced change of some kind, although the changes were not always improvements.
Why is it important to understand that changes occur in patterns?
it is important because every thing has to occur step by step
The split-ring reverses the sense in which the current is suplied to rotating coil after every half revolution?
due to comutator
Who is the governor of Nevada in 2011?
The governor of Nevada changes every couple years, but I believe that the current governor is Brian Sandoval.
Who are the permanent members of the United Nations?
The list changes every few years. Please see the accompanying link for the current list.
Why are rites of passage important for the Jews?
Rites of passage are important to every culture because they are the significant events that mark changes and growth in a person's life.
What is a frequency of ac signal in Pakistan?
The current which changes it direction after every half cycle is called alternating current(A.C) or Alternating current which produced by voltage source whose polarity keeps on reversing with time. By Shahnam qadeer
What is an electric current that periodically changes direction?
There are two types of electric current, DC or direct current and AC or alternating current. The power delivery to homes in most places in the world is AC or alternating current. This is where the electrons are pushed one way then back the other way with usually 100 or 120 changes in direction per second. This produces 50 or 60 forward/back cycles every second called 50Hz or 60Hz.
Why do you celebrate EDSA revolution?
EDSA revolution plays a very important role to the present bureaucracy and political system of the country.It is actually a manifestation of freedom,unity and nationalism of every Filipino to the country.
What is the Current value of all gold at For Knox?
The value of the gold held in Fort Knox changes every day because the price of gold changes every day. Current estimates of holdings are 147.4 MILLION ounces Troy in gold. The current spot price of gold is $1,126.40 per ounce, multiply that by the Knox's holdings for your answer. NOTE: The Federal Reserve Bank of New York actually holds more gold then Fort Knox does.
