Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. Electric Field Intensity in Capacitor. Where, E is the electric field. If the switch is always open, the start capacitor is not part of the circuit, so the motor does not start. These motors are used for the loads of higher inertia where frequent starting is required. If the switch is always closed, the start capacitor is always in the circuit, so the motor windings will likely burn out. If a motor does not start, the capacitor is far more likely the problem than the switch. As a result of Faraday's achievements in the field of electricity, the unit of measurement for capacitors, or capacitance, became known as the farad.
