Integrated Physics and Chemistry TEKS Correlations
(6) Science concepts. The student knows the impact of energy transformations in
everyday life. The student is expected to:
(F)investigate and compare series and parallel circuits;

106. The electrical circuits in houses are usually wired in parallel because 

circuit breakers can be safely used with parallel circuits
the flow of current is continuous when appliances are turned off
the current produced is less expensive to use in houses
series circuits produce too much current to be safely used in houses
Students have actually been working with circuits since grade 5. In high school we should
continue to have students work with circuits to so that they can truly understand Ohm’s law,
and not just plug in numbers.
