How is the number of house of representatives determined in legislative branch?
It is determined by population of each state
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.
How many 20 amp branch circuits are required for appliances the minimum?
The number of 20 amp branch circuits required for appliances depends on the total electrical load of the appliances. A general rule is to have one 20 amp circuit for every 600-700 square feet of living space. It is best to consult with an electrician to determine the specific requirements for your appliances.
How many outlets are allowed on a 240V branch circuit?
The National Electrical Code (NEC) does not specify an exact number of outlets for a 240V branch circuit. However, it is generally recommended to limit the number of outlets to avoid overloading the circuit, typically suggesting a maximum of 12 to 16 outlets for a 15A or 20A circuit. The actual number can also depend on the specific load requirements of the devices being used. Always ensure that the total load does not exceed the circuit's capacity.
How is the total current in a parallel circuit worked out?
You add up the currents in each branch. The current in each branch is just (voltage acrossd the parallel circuit)/(resistance of that branch) . ==================================== If you'd rather do it the more elegant way, then . . . -- Write down the reciprocal of the resistance of each branch. -- Add up the reciprocals. -- Take the reciprocal of the sum. The number you have now is the 'effective' resistance of the parallel circuit ... the single resistance that it looks like electrically. -- The total current through the parallel circuit is (voltage acrossd the parallel circuit)/(effective resistace of the parallel circuit) .
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.
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
What is the number of plugs can a 15 amp circuit handle?
A 15 amp circuit can handle approximately 1440 watts of power. To determine the number of plugs it can handle, divide the total wattage of the devices plugged in by 1440 to ensure that the circuit is not overloaded.
What Happens To The Overall Current Of The Circuit If The Number Of Receivers (and Thus The Number Of Branches) Is Doubled?
If the number of receivers (branches) in a circuit is doubled, the overall current of the circuit would also double, assuming that the voltage remains constant. This is because current is divided equally among the branches in a series circuit, so increasing the number of branches would result in each branch carrying less current if the overall current remained the same.
What is the max number of luminaries that can be installed on a 20-amp 277-volt branch circuit?
The maximum number of luminaries that can be installed on a 20-amp, 277-volt branch circuit depends on the wattage of the individual luminaries. To calculate this, first determine the total wattage capacity of the circuit, which is 20 amps multiplied by 277 volts, equaling 5540 watts. Then, divide this total wattage by the wattage of each luminary to find the maximum number of units that can be installed without exceeding the circuit's capacity. It's also essential to consider the NEC guidelines, typically allowing for a maximum of 80% of the circuit's capacity for continuous loads, which would further reduce the number of luminaries.
A total of 3500 square feet of occupied area the minimum number of 15-ampere lighting branch circuits is?
To determine the minimum number of 15-ampere lighting branch circuits required for a 3,500 square foot occupied area, you can refer to the National Electrical Code (NEC). Typically, one 15-amp circuit can handle up to 1,500 watts of lighting. Assuming a general guideline of 3 watts per square foot for lighting, you would need approximately 11,667 watts for 3,500 square feet, which translates to about 8 circuits (11,667 watts ÷ 1,500 watts per circuit). Thus, a minimum of 8 lighting branch circuits is recommended.
