Does the individual branch current depend upon the number of branches in a parallel circuit?
No. It only depends on the potential difference between the ends of the individual branch. If this is the power supply voltage, then the number of other branches doesn't matter.
Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
Why home winding in parallel?
For any appliance or lamp to operate at its rated power, it must be subjected to its rated voltage. Every branch of a parallel circuit is subjected to the same (supply) voltage. This is the main reason; the secondary reason is that any break in a series circuit will de-energise all the appliances connected to it!
Is the trolley busway considered to be a feeder or a branch circuit?
Feeder because the trolley will have overcurrent protection. Branch circuit is the final OCD to the load.
Can each branch in a parallel circuit may hold several resistors?
Yes, but then it would be a 'series-parallel' circuit, not a 'parallel' circuit!
How do you find the branch current in parallel circuit?
For each individual branch, you can use Ohm's Law - just divide the voltage by the resistance.
What is a branching circuit?
Each of the circuit breakers in the service panel controls electricity on a branch circuit. A branch circuit is typically a loop of wire that runs from the service panel, out to receptacles, light fixtures, appliances, etc. and back again.
How is a total current in a parallel circuit worked out?
sum the individual branch currents
What is the difference between a run and a circuit?
run in a electrical system means a wiring & conduit runs coming from Panel Board Circuit Breaker to its branch circuit loads in a circuit. while circuit is a designated number of branch breaker in a panel board where power load was individual connected.
Do individual lines in a parallel circuit have different currents flowing through them?
They can. The current in each "line" (correctly, *branch*) depends on (i) the applied voltage and (ii) the individual resistance in each branch. If the branch resistances are different, the branch currents will be different. Ohm's Law will let you calculate the individual currents.
What are the main parts of a household circuit?
One main part of any household branch circuit is its circuit breaker. It is designed to protect the electrical circuit from damage caused by current overloads or short circuits. It is designed to disconnect the electrical flow within a few milliseconds if it detects certain electrical faults. Then, to be able to provide power to the appliances and lights in the house, there must be fixed outlets and socket outlets supplied by the various branch circuits. Nothing can be provided with electrical power unless there is a main breaker panel to contain all the separate circuit breakers and also to provide the house with a main power on-off switch.

How much voltage is 15 amps?
How many watts can be supplied depends on the voltage of the branch circuit.Because a normal circuit breaker should only be loaded to 80 percent of its trip rating, then 0.80 X 15 = 12 amps.Assuming a 120 volt, 15 amp branch circuit, the maximum total wattage that can safely be supplied to all appliances connected to that circuit is (120 volts x 12 amps) = 1440watts.Assuming a 240 volt, 15 amp branch circuit, the maximum total wattage that can safely be supplied to all appliances connected to that circuit is (240 volts x 12 amps) = 2880watts.However, the 80% quoted is true for continuous loads only. If the appliances being switched on and off on a particular circuit never run continuously all at the same time, their individual wattages when totalled-up can, in fact exceed that 80% figure, because a non-continuously-loaded breaker may have 100% of its rating applied to it for short periods such that it does not become "warm"...As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Do all branches in a parallel circuit have to be on?
No, they do not. Think of it this way. Your house is one huge parallel circuit. Not every branch is on all the time. You turn switches on and off to turn individual branches on and off at will.
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.
