The document discusses the differences between series and parallel resistors in electric circuits, focusing on their configurations, current flow, and equivalent resistance calculation. It explains that in series circuits, resistors are connected in a sequence, summing up resistance values, while in parallel circuits, resistors are connected side by side, reducing total resistance. Ohm's law is also highlighted to assist in calculations involving voltage, current, and resistance in circuits.

10. RESISTORS IN
SERIES.

12. One significant difference between
series and parallel resistors entails
the flow of current through
elements. In a series connection,
resistors follow each other, allowing
current to pass through each
resistor (Thomas, 2010).

13. When the resistance values of each
element are summed up, we
calculate total resistance in series
resistor (Thomas, 2010).

14. RESISTORS IN PARALLEL

15. RESISTORS IN PARALLEL
The total current flows through the resistance by
moving parallel to one another. We add reciprocal
resistance values of each element and then invert
the answer to establish total cable resistance
(Proenca, 2008).

16. RESISTORS IN PARALLEL
In this case, the resistance power decreases: it is
lower than the resistance values of the smallest
resistor. Therefore, it is more beneficial to connect
wires and other devices in parallel rather than just
connecting complements in series (Proenca, 2008).

OHMS LAW

18. 18
OHMS LAW
V = I x R, where V is voltage, R is resistance, and I is current. This
provides a formula to help students solve Kirchhoff's current rule
algebraically. In addition to calculating the current drawn from the
supply when batteries are connected in parallel, you can also
calculate the voltage applied across parallel-connected resistors. The
current drawn from the source was calculated as the voltage applied
to the two parallel cells divided by the overall resistance of the
circuits (Nontsikiza, 2022)
