( R_T = 120\ \Omega ) ( I = 12 / 120 = 0.1\ \textA ) ( V_\texteach = 0.1 \times 40 = 4.0\ \textV )
This is where many students get stuck when looking for an answer key. The DC Circuit Builder often asks for the voltage across each specific resistor. This requires using Ohm's Law again, but applied to the individual component. dc circuit builder series circuit answer key
The first step in any series circuit problem is finding the equivalent resistance. Because all resistors are in a single path, their values simply add together. ( R_T = 120\ \Omega ) ( I = 12 / 120 = 0
