USING THE LAWS OF ALTERNATING CURRENT CIRCUIT ELECTRICITY APPLYING ELECTRICAL BASICS By Sri Wahyuni, SPd.

DIRECTION Participant be able to: Explain Ohm Law Explain Law Resources Electrical Explaining Prices Cash pace Teknologi dan Rekayasa

Ohm Law When the power source voltage 1 volt associated with the constraints of 1 Ohm, so the flow currents of 1 ampere. Teknologi dan Rekayasa

Where: V = Voltage in Volt R = Obstacles in Ohm V = I x R I = Current in Ampere R = Obstacles in Ohm Teknologi dan Rekayasa

Electrical Strength Law Given the power symbol and the letter P in Watt. Ohm's law formula can be written for the equality of power, namely: P = U x I Where : P = Power in Watt U = Voltage in Volt. I = Currents in Ampere Teknologi dan Rekayasa

EXPLAINING PRICES CASH PACE Right Value Value wave voltage can be in writing: V = Em Sin ωt This price is the value right, in the notation with a small letter. For AC currents, the value right with: i = Im sin ωt e = Em sin ωt Teknologi dan Rekayasa

Description: i = current rates as soon e = value right voltage Im = Maximum Flow Rates (Peak) Em = Value Maximum Voltage (Peak) sin ωt = Corner of the applied wave Teknologi dan Rekayasa

Vef = effective voltage (V) Vm = maximum voltage (V) Effective Value Vef = effective voltage (V) Vm = maximum voltage (V) ief = effective flow (A) im = maximum flow (A) Teknologi dan Rekayasa

Maximum Value and the Average Vr = average voltage (V) Vm = maximum voltage (V) ir = average flow (A) im = maximum flow (A) Teknologi dan Rekayasa
