Investigating the current - potential difference relationship for a metal wire. Aim: To design an experiment that will facilitate an I - V Graph to be ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in

technology involved the capsulation of the sun’s rays through panels of photovoltaic (PV) cells. The encapsulated energy charged a wet cell battery‚ controlled by battery control unit (BCU). It produce direct current (DC) power to run a DC appliances. Additionally‚ DC current can be converted alternating current (AC) to run AC appliances. These applications tested by the PGSEP. The PGSEP was confident that this application able to solve the Philippine’s rural electrification needs most especially in the

The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move due to voltage of the battery‚so the battery causes an electric field which make the electrons experience a force because of that field. The current flow on the opposite direction

The above requirements are not fulfilled in scalar control‚ where only angular speed (frequency) and magnitudes of flux‚ current and voltage vectors are adjusted. Instantaneous positions of these vectors are not controlled. Therefore‚ space vector control methods have been strongly developed. In this case‚ not only angular speed (frequency) and magnitudes of flux‚ current and voltage vectors‚ but also instantaneous position of these vectors is controlled. This ensures excellent dynamic and
