the field is given by the direction of that force. Electric fields contain electrical energy with energy density proportional to the square of the field amplitude. The electric field is to charge as gravitational acceleration is to mass and force density is to volume. 1. Suppose that two point charges‚ each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them. Given: Q1 = 1.00 C Q2 = 1.00 C

affordable and reliable‚ have flexibility of control‚ and offer significant electrical energy savings through greatly reduced electric bills. They are used in a wide variety of applications for various reasons. For example‚ they are the most effective energy savers in pump and fan applications; they enhance process operations‚ particularly where flow control is involved. VFDs provide soft-start capabilities‚ which decrease electrical stresses and line voltage sags associated with full voltage motor start-ups

1 A Voltage-Controlled Oscillator (VCO) is a circuit that provides a varying output signal (typically of square-wave or triangular-wave form) whose frequency can be adjusted over a range controlled by a dc voltage. An example of a VCO is the 566 IC unit‚ which contains circuitry to generate both squarewave and triangular-wave signals whose frequency is set by an external resistor and capacitor and then varied by an applied dc voltage. Figure (1) shows that the 566 contains current sources to charge

ENGR. JAY S. VILLAN‚ MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have around the house‚ and anyone who plans on doing electrical repairs should most definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in

connected to a power source is called the primary winding or input winding. The winding connected to the loads is called the secondary winding or output winding. Introduction The open-circuit test‚ or "no-load test"‚ is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. In this experiment‚ open-circuit test is conducted on single-phase and three-phase transformer to determine the iron core resistance‚ Rc and magnetized reactance
