  1. Arus DCAnalisis Rangkaian DC Firdaus Sulaiman

  2. Fundamental quantities • Voltage — potential difference bet. 2 points • “across” quantity • analogous to ‘pressure’ between two points • Current — flow of charge through a material • “through” quantity • analogous to fluid flowing along a pipe

  3. Units of measurement • Voltage: volt (V) • Current: ampere (A) • NOT Volt, Ampere!!

  4. Direction and polarity • Current direction indicates the direction of flow of positive charge • Voltage polarity indicates the relative potential between 2 points: + assigned to a higher potential point; and – assigned to a lower potential point. • NOTE: Direction and polarity are arbitrarily assigned on circuit diagrams. Actual direction and polarity will be governed by the sign of the value.
