Question

part 6 - electronics information

in the circuit shown in the
illustration, the battery
illuminates a lamp and
sounds a horn. opening
switch 2 will
a short out both the
horn and the lamp.
b activate the horn and
turn off the lamp.
c silence the horn and
leave the lamp on.
d alternate power
between the lamp
and the horn.
click the button or type the letter next to your answer.

Explanation:

In the circuit, the horn is in parallel with a switch (Switch 2), and the lamp is in a separate branch. When Switch 2 is open, the horn's path is broken (so it's silent), but the lamp's circuit (through the main path with Switch 1, assuming Switch 1 is closed) remains, so the lamp stays on. Option A is wrong as it doesn't short them. Option B is wrong as the horn won't activate. Option D is wrong as power doesn't alternate.

Answer:

C. silence the horn and leave the lamp on.
