July 11th, 2013 10:21 PM #41After learning Thevenin's Theorem ... they also teach Norton's Theorem which states
Any linear electrical network with voltage and current sources and only resistances can be replaced at terminals A-B by an equivalent current source Ino in parallel connection with an equivalent resistance Rno.

Prove first that the battery is a resistive load. kung hindi, parallel connection yan.

July 11th, 2013 10:27 PM #44when you only have two components in a circuit, e.g, a battery and a motor, the connection is both series and parallel
series because they have the same current, parallel because they have the same voltage

We could not consider the dead/low battery as a source kasi current is flowing into it. Saka sa set-up na jump-start, physically naroon lang yung dead/low battery but electrically, it is not functioning as a battery but another resistor or load.
BTT: I think yung mga commercial jumper ratings are good enough. Ang importante, maganda maganda ang quality ng cable at maganda pagka crimp ng clamp.

Granting na considered as resistive load ang dead battery, edi tama nga mga mekaniko daig pa nila ang ee or ece graduate.

July 11th, 2013 10:36 PM #47maybe ... old folks say "series" because it is easier to remember
btt: on cheaper jumper cables, the usual fault is the crimping ... soldering the copper conductor to the clamp will fix it

July 11th, 2013 10:43 PM #49Haha.. pinag debatehan pa talaga ang series o parallel
In Series, the current throughout each components is the same
While in Parallel, the Voltage is the same across all components be a load or a second battery.
As for the battery in parallel, it will equalize kung medyo mahina yung isa.
Kung AC circuits yan dyan kayo mag debate. The battery will now consist of capacitor resistor and inductor (battery impedance), while the starter will be purely inductive.

Sir, question lang. Pag ba sinabing dead battery as in zero(0) ang voltage reading nyan?
