Why should the voltage drops (electrical potential differences) across the resistors connected in parallel be the same?
Homework Answers
The resistors connected in parallel are connected such that their positive terminals and negative terminals respectively are connected together.
The potential difference across each resistor is the same because each is connected directly across the battery terminals.The current that enters a point must be equal to the total current leaving that point.

Using Matlab When several resistors are connected in an electrical circuit in parallel, the current through each of them is given by in=vs/Rnwhere in and Rn are the current through resistor n and its resistance, respectively, and vs is the source voltage. The equivalent resistance, Req, can be determined from the equation 1/Req=1/R1+1/R2+1/R3+.......+1/Rn. The source current is given by is , and the power, Pn, dissipated in each resistor is given by . is=vs/Req, and Pn=vsin. Write a program in...
