Only if the resistances of all the branches are the same.

RParallel = 1 / SummationI=1toN (1 / RI)

This simplifies to RI / N only if all RI's have the same value.

4 How do you determine current in a parallel DC circuit?

The current in each individual component of the parallel circuit is equal to (voltage across the combined group of parallel components) / (individual component's resistance). The total current is the sum of the individual currents. ============================== Another approach is to first calculate the combined effective resistance of the group of parallel components. -- take the reciprocal of each individual resistance -- add all the reciprocals -- the combined effective resistance is the reciprocal of the sum. Then, the total current through the parallel circuit is (voltage across the parallel circuit) / (combined effective resistance of the components).


Why is resistance less when resistors are join in parallel?

What do you mean? In a parallel circuit, the combined (or effective) resistance is less than any individual 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.


If one branch of a parallel circuit has high resistance?

If one branch of a parallel circuit has high resistance, it will draw less current compared to branches with lower resistance. This means that most of the total current will flow through the lower-resistance branches. Consequently, the voltage across all branches remains the same, but the overall current provided by the power source will be affected, potentially resulting in decreased total current in 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 are parallel circuits characteristics?

Parallel circuits have multiple pathways for current to flow, meaning that if one component fails, the others can continue to function. The voltage is the same across all components in a parallel circuit, but the current is divided between the branches based on their resistance. The total resistance in a parallel circuit is less than the resistance of the individual branches.


Does the current split in parallel circuits affect the overall resistance in the circuit?

Yes, the current split in parallel circuits does affect the overall resistance in the circuit. In a parallel circuit, the total resistance decreases as more branches are added because the current has multiple paths to flow through, reducing the overall resistance.


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 when more branches are added to a parallel circuit?

Adding more branches to a parallel circuit decreases the overall resistance of the circuit. This leads to an increase in the total current flowing through the circuit as each branch provides an additional pathway for the current to flow. This results in a decrease in the total resistance and an increase in the overall current of the 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


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 happens to voltage and current in a parallel circuit?

-- The voltage between the ends of each parallel branch is the same. -- The current through each parallel branch is inversely proportional to the resistance of that branch. (It's the voltage divided by the resistance of the branch.)
