Name: Inquiry Question Can you design a circuit to specifications using a schematic? How can Ohm's Law help in the design? Can you test your design with ammeters and voltmeters? The fundamental building blocks of many circuits are resistors. Various components (such as resistors, light bulbs, and measuring devices) must often be connected together in intricate series and parallel arrangements to achieve specific operating values (precise currents so that parts function efficiently). Being able to read and create schematics is a necessary tool with electronics design and repair. Let's start with the basics and build. m DO mmmm 275 22 K 2222A Switch LED 2021-09-21 Page 1 of 12WCLN.ca Part 1: Core Open the PHET sim entitled Circuit Consrruction Kit: DC, https:// construction-kit-de/latest/circuit-construction-kit-de_en.html het.colorado.edu/sims/html/circuit- I.
