BASIC ELECTRONICS - OD1633 - LESSON 1/TASK 2
Once the equivalent resistance is known, a new circuit is drawn consisting
of a single resistor (to represent the equivalent resistance) and the
voltage source, as shown in view B.
is equal to the source voltage.
Rule 2: The current through a branch of a parallel network is inversely
proportional to the amount of resistance of the branch.
Rule 4: The total resistance of a parallel circuit is found by the general
or one of the formulas derived from this general formula.
c. Solving Parallel Circuit Problems.
Problems involving the
determination of resistance, voltage, current, and power in a parallel
circuit are solved as simply as in a series circuit. The procedure is the
same: (1) draw the circuit diagram, (2) state the values given and the
values to be found, (3) select the equations to be used in solving for the
unknown quantities, based upon the known quantities, and (4) substitute the
known values in the equation you have selected and solve for the unknown
