To find the current in a complex circuit it is necessary to know?
Nikkilepew
the source voltage and the total impedance
AnswerA 'complex circuit' describes a category of circuit that is neither series, parallel, nor series-parallel. A relatively-simple example of a complex circuit is a Wheatstone Bridge. You cannot analyse or resolve a complex circuit using the techniques used to analyse and resolve series, parallel, or series-parallel circuit. Instead you must use one or other of the various electrical theorems. For example, to determine the currents flowing in a Wheatstone Bridge circuit, you could use Kirchhoff's Laws or Thevenin's Theorem.

How do you find the branch current in parallel circuit?
For each individual branch, you can use Ohm's Law - just divide the voltage by the resistance.
Is voltage and current proportional to each other?
Yes, in accordance with Ohms law. Accross a given resistance, current will increase directly proportional to the increase in Voltage. Voltage(Volts) = Current (in Amps)x Resistance(in Ohms) You can transpose the formula to find the unknown, given 2 of the values.
How do you find the current draw of an electrical circuit if you know the voltage and wattage of the device?
The answer you need is found in "Ohms Law." It is expressed like this: Current = watts divided by volts Watts = Volts multiplied by current Volts = Watts divided by current. I recommend you look into the hobby of Amateur Radio and put your knowledge of electronics to a fun use. My wife and I are both 'hams' and love the hobby!
Does voltage regulator increase or decrease the current input?
A DC voltage regulator gives a constant output voltage provided the input voltage is at least 1.5 v higher, up to a given limit. The input current is slightly more than the load current, because a small amoutn of current is needed for the voltage regulator circuit. Check the datasheet of the component which you are using to find the limits. 7805 IC can give upto 1A of current if there is adequete heatsinking.
Does the current stay the same in a parallel circuit and a series circuit?
A series circuit allows only one path for the electron path to follow. This type of circuit is found in something like Christmas tree lights. But a parallel circuit allows the 2 or more path for the electron path to follow. This is primarily used in households. So no, they are not the same electrons because they are two completely different circuits.
What is meant by calculate the equivalent resistance of the circuit from the measured potential difference across the battery and the current through the battery is there a formula for this?
In a complex circuit with various elements (resistors, capacitors etc.) and one battery, the various circut elements contribute to draw a certain amount of current "I"from the battery at some terminal voltage "V". The "equivalent" resistance of the various circuit elements is that resistance "R" which will draw the same current , at the same terminal voltage, as the complex circuit. So to find "R" you simply imagine replacing the complex circuit with "R" by attaching "R" across the terminals of the battery and use Ohms law to find "R" , demanding "I" and "V" are the same. So then R = V/I.
How do you find the current in a wire?
Open the circuit and put an amp meter in series. There are clamp on current meters. You don't need to break the circuit.
What do you find out about the current at different places in the series circuit?
The current at different places in a series circuit is the same. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of this is that the current at every point in a series circuit is the same.
How do you find power in a circuit?
P=IV Power=current x voltage
Is a television a series circuit?
A television set is a complex group of circuits where we find components in series and others that are in parallel.
An electric DC circuit is attached to a 12 volt battery and has a 3 ohm resistor in it find the current flowing through the circuit?
If the 3-ohm resistor is the ONLY thing in the circuit, then the current flowing through it is (12 volts)/(3 ohms) = 4 amperes. If there are other things in the circuit besides the resistor, then the current depends on all of them.
Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
How could you calculate the resistance of a circuit?
A variety of techniques can be used. Node-Voltage and Mesh-current (or Loop-current) methods, for example. See related link for examples. If there is a single voltage source in the model, then find the current supplied, and Resistance = Voltage/Current. {R = V/I} You could simulate/ model the circuit on a computer then apply the power profile and a current value will be calculated. Or if you have the circuit working, Place an amp meter into the circuit and measure the current. V/i = resistance.
How do you find the value of a apartment complex?
To find out the current value of an apartment complex, you would need to hire a qualified real estate appraiser to provide you with an appraisal and operating income on the property.
How the superposition theorem is used to find the currents in a circuit supply by more than one voltage source?
1.Put a short circuit instead of voltage source 1 and find what you want with taking direction of current in that element(ris.ind.cap.) 2.puta short circuit instead of voltage source 2 and find what you want with taking direction of current in that element(ris.ind.cap.) 3.add current 1 and 2 for any element.
Where circuit breaker are used?
Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
Wt is source current and sink current in a DC regulator?
The source current is that current which will leave the DC regulator and travel to the load circuit connected to it. The sink current is that current which may come from the load circuit and attempt to find a path through the ground through the regulator. Generally most regulators are designed to just source current to a load and are not setup to receive current back(sink it)
