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?
To light up a circuit, you need to close the circuit by turning on all switches that are in the same path as the lightbulb. This ensures that electricity can flow through the entire circuit and reach the lightbulb.
No, you cannot turn on any switch in the circuit to light up the lightbulb. You need to turn on all switches that are in the same path as the lightbulb to close the circuit and allow electricity to flow through.
If you turn on a switch that is not in the same path as the lightbulb, the circuit will not be closed and the lightbulb will not light up. This is because electricity cannot flow through a circuit that is not closed.
Yes, you can turn on multiple switches at the same time to light up the lightbulb. As long as all switches that are in the same path as the lightbulb are turned on, the circuit will be closed and the lightbulb will light up.
To turn off the lightbulb, you need to open the circuit by turning off all switches that are in the same path as the lightbulb. This will break the flow of electricity and the lightbulb will turn off.
