The effective conductance is the sum of the individual conductances. "Conductance" is the reciprocal of resistance. Expressing the rule in terms of resistances:
1 / R = 1 / R1 + 1 / R2 + 1 / R3 ...
Where "R" is the effective (combined) resistance, and R1, R2, etc. are the individual resistances.
What else can I help you with?
How do you combine two or more circuits to achieve greater amperage ie. combine two 20 amp circuits to achieve a 40 amp circuit?
If you mean "combining circuits" as in connecting two or more circuits in parallel, this is only allowed by the National Electrical Code when the wires are at least size 1/0 (about 150 amps) You are not allowed to parallel conductors smaller than 1/0 If you meant something else, you need to clarify the question
Why are resistances parallel to short circuits neglected in a circuit?
You can consider a short circuit to be a resistor with R=0 Ohms. It is then clear by the equation for calculation of parallel resistance that the combined resistance of a resistor in parallel to a short circuit is 0. Consider the following example with R1= 1k Ohms and R2= 0 Ohms: Rtotal = R1*R2 / (R1+R2) = R1*0 / R1 = 0 Ohms.
Where are parallel circuits used?
Parallel circuits are used when there are many electronics on the same circuit, such as Christmas lights, for example. If they were on a series circuit, if one bulb went out all of them would go out. In your home, parallel circuits allow you to turn any electrical device on or off, independently of the others.
Where are parallel circuits found?
parallel circuits can be used for lots of things.Things such as : . Christmas tree lights False for A+
What is a fact for parallel circuits for kids?
A parallel circuit is a circuit that takes both legs to make a load.
What is made up of series and parallel circuits?
that is called a perfect circuit
What are the differences between series and parallel circuits in terms of their configurations and electrical properties?
In a series circuit, components are connected in a single path, while in a parallel circuit, components are connected in multiple paths. In terms of electrical properties, series circuits have the same current flowing through all components, while parallel circuits have different currents flowing through each component. Additionally, in series circuits, the total resistance is the sum of individual resistances, while in parallel circuits, the total resistance is less than the smallest individual resistance.
Can parallel circuits be used instead of fuses?
No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
How do series circuits and parallel circuits compare?
In series circuits, the current flows through each component sequentially, so if one component fails, the entire circuit will fail. In parallel circuits, each component has its own separate branch, so if one component fails, the others will continue to operate. Additionally, the total resistance in a series circuit is the sum of individual resistances, while in a parallel circuit, the total resistance is less than the smallest individual resistance.
What term remains the same across all the resistances in a parallel combination of resistances?
The voltage across the resistors will remain constant.
What is the apparent rue for combing resistances in parallel?
let the total resistance = R(t) 1/R(t) = 1/R1 + 1/R2 + 1/R3 + ... where R1, R2, R3, etc. are the individual resistors that are set up in the parallel circuit. Hope that helped!
What are the types of circuits?
The types of circuits are series and parallel!
What types of circuits are in a cell phone?
parallel circuits
What is the name of the circuit that is neither parallel nor series?
FEEDBACK CIRCUITS. In addition to parallel and series circuits, there are also closed and short circuits.
Does a parallel circuit have more than 1 resistor?
Parallel circuits normally have more than one resistor. Basically parallel circuits are circuits where the current has more than path to follow. However, there are parallel circuits where there are two switches rather than two resistors.
What are the multiple resistance circuits?
Multiple resistance circuits are electrical circuits that contain more than one resistor connected in various configurations, such as series, parallel, or a combination of both. These circuits are commonly used in electronic devices and systems to control the flow of current and voltage. The total resistance in a multiple resistance circuit can be calculated using different formulas depending on the arrangement of the resistors.
How would you connect several resistances if you wish to increase the current?
Connect it in Parallel.
