Q:Can you wire capacitors in series?A:When capacitors are connected in series, the total capacitance is less than anyone of the series capacitors' individual capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors.

Q:What is the formula for calculating capacitance?A:The definition of capacitance is given by this equation:capacitance C, measured in farads, equals charge Q, measured in coulombs, divided by voltage V, measured in volts. The capacitance is based on the physical characteristics of the capacitor.

Q:Does the series capacitor have the same charge?A:Although the voltage drop across each capacitor value is different, different capacitor plate between the coulomb charge will be equal, because of the existence of the same amount of current in a series circuit of capacitance is provided the same number or the number of electrons.

Q:What are film capacitors?A:Film capacitors are capacitors which use a thin plastic film as the dielectric. This film is made extremely thin using a sophisticated film drawing process. Once the film is manufactured, it may be metallized or left untreated, depending on the needed properties of the capacitor. Electrodes are then added and the assembly is mounted into a case which protects it from e...

Q:What is the key advantage of film capacitor?A:A key advantage of modern film capacitor internal construction is direct contact to the electrodes on both ends of the winding.

You might see 40+5 MFD, meaning that one side is 40 microf...

Q:Can I use a run capacitor in place of a starting capacitor? A:Yes, you can use run capacitors as start capacitors.

Q:What is the purpose of capacitor in a motor? A:Capacitor is used for developing starting torque. For improving power factor of motors. For smooth and noise less operation. It also acts as a filter.

Q:How is capacitance measured? A:Capacitors are rated by the storing characteristic referred to as capacitance which is measured by the scientific unit, farad. Each capacitor will have a fixed value that they are rated at storing which can be used in combination with other capacitors in a capacitor bank when there is a significant demand to absorb or correct AC power faults or to output DC power.

Q:How we define the Power Factor? A:The Power Factor is an indicator of the quality of design and management of an electrical installation. It relies on two very basic notions: active and apparent power.The active power P (kW) is the real power transmitted to loads such as motors, lamps, heaters, and computers. The electrical active power is transformed into mechanical power, heat or light.In a ci...

Q:How capacitors store energy? A:If you find capacitors mysterious and weird, and they don't really make sense to you, try thinking about gravity instead. Suppose you're standing at the bottom of some steps and you decide to start climbing. You have to heave your body up, against Earth's gravity, which is an attractive (pulling) force. As physicists say, you have to "do work" to climb a ladder (wo...

Q:How to calculate the power capacitor size? A：We need to know the reactive power consumption in order to properly calculate the size. If you use simple load, such as electric motor, inductors or resistive loads, equipment which does not require adjustable-speed-drive to control motors speed, you can calculate the capacitor bank size you need by observing your electricity meter.

Q:If I can't find a replacement for my dual run capacitor, can I use two separate run capacitors? A：The dual run capacitor design's only advantage is that it comes in a small package with only 3 connections. There is no other difference. If there is enough mounting space, using two separate run capacitors in place of your original dual run capacitor is an acceptable practice.

A:The normal starting capacitor like this: Voltage:110-330V (110V/125V,165V,220/250V,330V) When you replace a starting capacitor,you must use the same capacitance and frequency as the original one.As for the voltage,you can choose a voltage in the range of the operational voltage of the motor;Capacitor voltage peak voltage indicator is...

Q:What's the function of power capacitor? A:It is mainly used for enhancing the power factor of the network,reducing the reactive loss and improving the voltage quality.For maximum power, voltage and current must be in phase, with their peaks coincident.In a factory, with a lot of motors, the motors use coils and present an inductive load, so voltage and current get out of phase, voltage leads.So ...

Q:How do I know if my start capacitor is bad? A:Most failures are one of two types: 1."The start cap blew its guts out!" This is what we call catastrophic failure. It is usually caused by an electric motor's starting circuit being engaged too long for the intermittent duty rating of a start cap. 2. The top of it has literally been blown off, and the insides have been partially or fully eje...
