____ occurs when the switch is open resulting in the input to the voltage-sensing circuit of the control module being susceptible to electrical noise that may cause the control module to misread the switch state.
A) Pull-up circuiting
B) Pull-down circuiting
C) Floating
D) Multiplex switching

Question

Quizplus · Accepted Answer

When a switch is open, it creates a situation known as "floating" where there is no clear voltage state in the circuit. This can make the input to the voltage-sensing circuit susceptible to electrical noise, leading to misreading of the switch state. Pull-up and pull-down circuiting are mechanisms used to establish a clear voltage state when a switch is open or closed, respectively. Multiplex switching is a type of circuit used in electronics to allow multiple devices to share a single input/output line.
