How is voltage spread out in series circuit?
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
What is true about the sum of the voltages across the components in a circuit compared to the voltage of the cell?
voltage is devided only in series circuit and is the same at the parallel circuit
Kirchoff's law that states the sum of the currents entering the node is equal to the sum of the currents leaving the node on a parallel circuit?
KCL (Kirchoff's Current Law) applies to any circuit, not just parallel circuits. The sum of the currents entering a node will always equal the sum of the currents leaving the node. KVL states that the sum of the voltages around a closed loop is always zero.
What is caused by a short circuit?
A short circuit is a low resistance connection where one is unexpected. It causes a diversion of current from the intended load, and, since it is usually a higher than expected current, it often causes the protective device (fuse, circuit breaker, or relay control logic) to trip.
How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
How does you caluclate the Horse power in 250 amp circuit breaker?
First of all, circuit breakers are rated in amps, not horsepower. Theequivalent between HP and electricity is 1 HP = 746 watts. That is a 1 HP motor requires 746 watts of power to operate it , regardless of the voltage. If you have a 250 amp circuit breaker, it is likely the main breaker to your residential panel. (?) The potential HP the panel could provide could be determined by multiplying the 250 amps times the panels voltage (208,220, 240) and divide the sum by 746.
What size breaker do I need on the main panel to run a 2-60 amp breakers and 2-40 amp breakers on a sub panel?
You need to calculate how much the total current is likely to be at any moment. It's probable that the total load will be less than the sum of the individual breakers, 200 amps, but how much less depends on local conditions.
The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit.?
True...!
What amp circuit breaker should be used for a 120v 2.5 amp appliance?
If the appliance is just to be plugged into a circuit with multiple outlets then you just need to make sure that the sum of currents for all devices on the circuit are less than the rated current. A rule of thumb is total current should be no greater than 80% of the rated current. So you might have a 20 A breaker and several 2.5 A appliances on this circuit. If you have a dedicated circuit for the appliance you would only need to size the breaker for the maximum current being drawn by the appliance. If the appliance contained a motor then there might be a start-up current that might be as high as 15 amps so you would likely go to a 20 amp breaker for a safety margin. As a practical matter a dedicated circuit for an appliance in the 2.5 amp range should have a 15 amp breaker. I always install a 20 amp breaker just for added margin and possible future applications.
Can you add a 20 amp breaker to main breaker if total breaker amp is 320 amp Main breaker max is four 150 amp breaker?
Total amps or calculated load has nothing to do with the number of breakers and their sizes. It is more complicated than adding the sum of the breakers, if you do that you will see that they would exceed 200 amps.It is based on square footage for the general receptacle and lighting loads,3000 watts is allowed for small appliances and this is just the beginning.Some experienced electricians have trouble with the calculations.If you are trying to see if you have enough capacity for an addition or some upgraded equipment,and you have breaker space,the chances are you will be O.K. Overloading the service would cause the main to trip.
The applied voltage in a circuit equals the sum of the circuits individual what?
For a series circuit, the applied voltage equals the sum of the voltage drops
The sum of all the power drops in a series circuit must equal?
The sum of all the power drops in a series circuit must equal
What is the purpose of main switches?
The main breaker limits the overall current to the building. Most buildings have many branch circuits that sum to more current than the service is rated for. This is not a problem as all the branch circuits are not used under high current draws at the same time. The main breaker protects the main wiring in the meter and to the transformer, and the transformer itself, from heavy current loads. It also protects from shorts in the main distribution panel.
What is the purpose of a fuse in an electrical circuit?
The purpose of a fuse is to open an electronic circuit when current flow exceeds a certain amount, determined by the rating of the fuse. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.
What are four things to show a force is balanced?
The four things that show a force is balanced are as follows : SUM ( F sub x ) = 0.0 N SUN ( F sub y ) = 0.0 N SUM ( F sub z ) = 0.0 N SUM ( moments ) = 0.0 N - m
What is the sum of currents is known as?
The sum of currents in a circuit is known as total current, which is the combined flow of all individual currents passing through the circuit components. This total current is conserved in a series circuit where it remains constant throughout the circuit.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
