SUMMARY

The discussion focuses on determining which combinations of switches S1 and S2 will successfully close a circuit to turn on a light. The correct combinations identified are S1 = B and S2 = B, and S1 = A and S2 = A, as both scenarios allow current to flow through the switches. The conclusion is that the circuit requires both switches to be in the same state for the light to activate.

Homework Statement



Which combination(s) would allow the circuit below to turn on the light?

S1 = A and S2 = B
S1 = B and S2 = A
S1 = B and S2 = B
S1 = A and S2 = A

The Attempt at a Solution



I'm thinking that it would be true for the third and fourth ones when S1 and S2 are the same, so the current can flow through both switches. Otherwise, the circuit wouldn't be closed, no?

Yes, correct.
