How is resistance affected as more branches are added to a parallel circuit?

in a parallel circuit, the relationship of resistance is thus:
1/R1 + 1/R2 = 1/RT
where R1 and R2 are two resistors in parallel and RT is the total resistance in the circuit:
Using this, as more branches are added, the resistance decreases
This is because there is more ways for the current to flow and thus using the analogy of a water flow with a constraint on it (resistor in electrical circuits), a whole load of streams with the same constraint on each will allow more water through than one large stream with the same small constraint on it.

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.
What is a circuit with two or more branches for current to flow called?
Parallel circuit
What are the circuit effects due to a short circuit or open circuit?
It would depend on the circuit diagram. In some cases, the circuit would be incomplete (simplest case is a battery with a wire attached to just one terminal).Parallel branches that have a connection to the battery without going through other branches are independent of each other. Say you have two parallel branches and a battery. If you short circuit one of the branches, the other branch will not be affected but the battery will be (current through the battery would decrease because taking out a parallel branch increases resistance).In short, it would depend on the circuit diagram. Note that for a nanosecond, there would be current in an open circuit, but after this brief time there would be no current flow in the segment of the circuit that has been shorted.
What happens to supply voltage if additional resistance is connected in parallel circuit?
No change in supply voltage as additional resistance is connected in parallel circuit.
What is the three laws of parallel circuit?
The potential difference remains the same over the components in parallel and the current splits up proportianally to the components conductances. The components conductances add up to give the combined conductance of the parallel circuit. Conductance is 1 / resistance
How to calculate a parallel circuit with more than one load in its branches?
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.
A type of circuit in which current can branch off?
In a parallel circuit, current is divided between each of the 'branches', according to their resistance.
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.
Why if one branch in a parallel circuit is shorted all others will short?
A current checks less resistance path to flow. When one of parallel branches is shorted, it becomes have less resistance and whole the current will flow through it, means current before parallel branches and current after parallel branches becomes same, and all branches become short.
What is a circuit with two or more branches for current to flow called?
Parallel circuit
A circuit that has two or more branches for electrons to follow is a?
parallel circuit.
Is the sum of the resistance in a parallel circuit always excessds the total resistance in a circuit?
Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.

Why does the same voltage run through all the branches of a parallel circuit irrelevant of the different resistance appliances on those branches?
The same voltage is present but does not run. It is the current that could be described as "runniing" through the different branches. Just by definition, parallel circuits necessarily have the same voltage. It is architecture of the circuit.
How do the partial current behave in relation to the corresponding resistance value for parallel circuiting of resistors?
The ratio of current flow through individual branches of a parallel circuit is inversely proportional to the ratio of resistance of each branch.
Which circuit has different parts of the circuit on separate branches?
Any circuit that even has more than one branch is a parallel one.
what happens to current in a 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.
