Goal: Reasoning regarding circuits
Source: 283-565 circuit currents
Consider the circuit below. Which statement(s) is correct?
- IAB = IBD +
- IBC < IBD
- IBC > IBD
- 1 only
- 2 only
- 3 only
- 1 and 2
- 1 and 3
(4) Students should be encouraged to reason about the currents and not
calculate the value of the currents in circuits. Interestingly, if a
problem similar to this is given with the potential specified as a
number, many students will immediately calculate the currents.
