To find the current in a complex circuit it is necessary to know?
the source voltage and the total impedanceAnswerA '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.
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.
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.
What did you find out about the current at different places in parallel circuit?
Kirchhoff said that the sum of the currents leaving are the same as the current that entered. The current in any parallel branch depends on Ohms law. The voltage across the device divided by its' resistance equals the current.
How do you find power in parallel circuit?
Voltage will be same in all branches. Voltage= Current * Total Resistance
Current divider rule?
Ix = IT(Rp/Rx+Rp) where Ix is the current you are trying to find, IT is the total current, Rx is the resistor in question, Rp is/are the resistor(s) in parallel with the resistor in question.
What is the current flow in a 12VDC circuit with two 24 ohm resistors in parallel?
In a parallel circuit, the same (supply) voltage will appear across each branch. So, in your example, 12 V will appear across each of the 24-ohm resistors. To find the current through each resistor, then, you simply divide the supply voltage by the value of that resistor. Since the supply current is the sum of the two branch currents, to find the supply current, you simply add together the currents passing through each resistor.
How do you find current in a compound circuit with parallel and series circuits?
Current in a parallel circuit divides between the branches, depending on the relative impedance of each branch. Kirchoff's current law, which can be used to analyze that current, states simply that the sum of the currents entering and leaving a node, properly signed, always add up to zero.Current in a series circuit is the same at every point in the circuit. This is a consequence of Kirchoff's current law, because a node in a series circuit consists of only two conductors, and the sum of the currents at that node must be zero. By implication, then, all nodes in a series circuit must have the same current.Not asked, but discussed due to completeness, is Kirchoff's voltage law, which states that the signed sum of the voltage drops around a series circuit always add up to zero. A consequence of this is that the voltage across elements of a parallel circuit must be the same.
What do parallel circuit NOT have in common with series circuit?
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
Where might you find a parallel circuit?
In a science lab.

A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the current running through the 60 ohm resistor?
To calculate the current running through the 60 ohm resistor in a parallel circuit, you first need to find the total resistance of the circuit. For a parallel circuit, the reciprocal of the total resistance (1/RT) is equal to the sum of the reciprocals of the individual resistances (1/R1 + 1/R2 + 1/R3). Once you find the total resistance, you can use Ohm's Law (I = V/R) to calculate the current running through the 60 ohm resistor.

How do you find resistance when you have current and resistance total?
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
How do you find resistance in a circuit?
That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.
