How to calculate a parallel circuit with more than one load in its branches?

∙ 11y ago
If a 'parallel' circuit has more than one load in its (not "it's"!) branches, then it is not a parallel circuit, but a series-parallel circuit! To resolve the circuit, you must first resolve the total resistance of the loads within each branch.

Where do you put the switch in a parallel circuit?
Switches used in electrical circuits are wired in series with either a parallel or series load. In parallel loads, the switch is upstream from the parallel circuit, so that the switch will shut off all of the parallel circuits.
What is common to both thevenin and norton theorem?
To solve any D.C. circuit by using Thevenin Theorem,First of all load resistance RL is disconnected from the circuit and open circuit voltage across the circuit is calculated (known as Thevenin equivalent voltage)Secondly, the battery is removed by leaving behind its internal resistance. Now we calculate equivqlent resistance of the circuit ( called Thevenin equivalent resistance).Now we connect Thevenin Voltage in series with Equivalent resistance of the circuit and now connect load resistance across this circuit to calculate current flowing through the load resistance.Whereas in the case of using Norton theorem, we again remove the load resistance if any, and then short circuit these open terminals and calculate short circuit current Isc.Second step is same as in Thevenin theorem i.e. remove all sources of emf by replacing their internal resistances and calculate equivqalent resistance of the circuit.Lastly, join short circuit current source in parallel with equivalent resistance of the circuit. Now, we can calculate votage across the resistance which was connected in parallel with Isc.So, by knowing the open circuit voltage, we can calculate current flowing the resistance and on the other hand , by knowing the short curcuit current , we can calculate voltage across the resistance.
How is ammeter and voltmeter attached to a circuit?
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
What trouble that exist in parallel circuit if one of the load in parallel circuit is shorted?
when loads are connected in parallel it means that they share common nodes at both the ends i-e voltage across all the loads is the same. when one of the load in such a circuit is shorted i-e its voltage is made zero volts, voltage across the other loads goes to zero because of parallel connection and they gets shorted also.
Does each load in a parallel have the same circuit?
your moms a load in a parallel
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.
Does a battery last longer in a series or parallel circuit?
A battery doesn't see a series or parallel circuit. It just supplies the current that is demanded by the load be it a series or parallel load. Visualize that a single load across a battery is both a series and parallel load to the battery.
What is a fact for parallel circuits for kids?
A parallel circuit is a circuit that takes both legs to make a load.
A circuit with a separate path for each appliance is a?
A circuit with a separate path for each load is a dedicated circuit. <<>> A circuit with a separate path for each load is a parallel circuit.
What happen when a ammeter is placed in parallel with the circuit?
If an ammeter is placed in parallel with a a load on a circuit, the circuit can short out as the ammeter takes the place of the load, flowing freely through the meter. Never measure across a resister or other electronic load with an ammeter. Remember, ammeters are used in series while voltmeters are used in parallel.
Do you need a switch to control each load in a parallel circuit?
Yes.
What is the key difference between a parallel circuit and a series circuit?
A series circuit pretty much runs in one direction, with each item which uses a load on that circuit one after another in a series. Should one load go out (a lamp, for example) then the entire series is defunct. A parallel circuit has more than one way to run, has a parallel or tandem circuit, so that if one load (our lamp, again) should fail, the electricity has another path (or more) to get to other loads on the circuit.
Where do you put the switch in a parallel circuit?

What is the kind of circuit in which an electrical load may be disconnected without affecting other loads?
In a parallel circuit an electrical load may be disconnected without affecting other loads.
