Gerbang logika setara — Perancang rangkaian
Switches wired in series and in parallel behave exactly like logic gates, and this builder makes that equivalence explicit. Lay out a circuit of keys and a lamp, then watch the matching gate symbol and truth table appear beside it as you open and close each switch.
Cara memakai simulasi ini
- Load the standard AND, OR, NAND and NOR arrangements, or the three-key case
- Open and close each switch to drive the circuit yourself
- Draw a custom switch–lamp circuit and let the gate update to match
Yang perlu diamati
- The truth table fills in row by row as you step through every switch combination
- Series arrangements need every switch closed; parallel ones need only one
- NAND and NOR give exactly the inverse output of AND and OR for the same inputs
Fisika di baliknya
A lamp lights only when a complete conducting path exists. Two switches in series both have to be closed, which is the AND condition; two in parallel need only one closed, which is OR. Inverting the output — a switch that short-circuits the lamp — produces NAND and NOR. This is the bridge between circuit theory and Boolean algebra.
