On the Subject of Resistors
“It is easier to resist at the beginning than at the end.”
― Leonardo da Vinci, on procrastination
The module contains 2 input pins (A and B), 2 resistors, and 2 output pins (C and D). Follow the rules to make the correct connections. To make a connection, click one pin and then another. Press CLEAR to remove all connections.
Take the first digit of the bomb's serial number (or 0 if there are no digits). The primary input is A if even, B if odd.
Take the last digit of the bomb's serial number (or 0 if there are no digits). The primary output is C if even, D if odd.
The target resistance in Ω is calculated as follows:
Take the first two digits of the bomb's serial number.
e.g. 2E7X19 → 27, ZJ3MLN → 3, ABCDEF → 0
- For each battery present on the bomb (up to a max of 6), multiply by 10.
- Take the first two digits of the bomb's serial number.
Connect the primary input to the primary output, with the target resistance.
Note: all resistance values are checked to be within 5% accuracy.
If a lit FRK indicator is present, also connect the primary input to the other (secondary) output, with the target resistance.
Note: this means C and D will also be connected with some non-infinite resistance. This value is not checked as part of your solution, and so can be anything.
If step 5 did not apply and at least 1 D cell battery is present, connect the secondary input to the secondary output, with 0Ω resistance.
Press CHECK when finished to check the solution. All input/output pairs not mentioned should be disconnected.
