The buzzer only makes noise when the loop touches the wire because that contact completes an electrical circuit. When the loop connects with the wire, it allows current to flow through the buzzer, activating it and producing sound. If the loop is not touching the wire, the circuit remains open, preventing current from flowing and keeping the buzzer silent.
What else can I help you with?
What is the name of the game where there is a wavy line of metal and when any other metal contacts it a buzzer buzzes?
wire loop game
How would you connect a mini momentary pushbutton switch and a 12VDC backup buzzer using only one 9 volt battery?
Simply connect all three items in series. When the pushbutton switch is momentarily depressed, current flows in the loop. Since the 'power supply' is 25% short of the buzzer's rated operating voltage, the buzzer may or may not sound.
When a microphone gets too close to it's speaker why does it screech?
When a microphone gets too close to its speaker, it forms a feedback loop where sound picked up by the mic is re-amplified by the speaker. This continuous loop creates a high-pitched noise, known as feedback or screeching. Adjusting the distance or angle between the microphone and speaker helps prevent this issue.
Is there any rule that if I use an If in a loop then i cant use that if in another loop?
If your question makes sense at all, and it is about programming, then the answer is no.
What is the effect of the feed back on the performance of the control system?
Feedback is mainly desired for increased stability. An open loop system is very much prone to system parameter changes as well as to the environmental noise and other changes. On the other hand a feedback loop makes system insensitive and thus robust. Regards Farhan Shahid
What makes closed-loop op amp unstable?
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
What does the resistor in a steady hand game do?
In a steady hand game, the resistor is part of an electrical circuit that detects when the player touches the wire with the metal loop. When the loop makes contact with the wire, it completes the circuit, allowing current to flow. The resistor limits the amount of current passing through, which helps prevent damage to the circuit and ensures that the buzzer or light indicator activates only when the circuit is completed improperly. This design enhances the gameplay by providing an immediate response to mistakes.
Why does the amp make noise when you get too close?
It's called feedback. The microphone causes a loop, what is coming out if the amp is being asorbed by the mic, sent back to the amp and projected again. The loop causes a squeal.
Where the phased locked loop is used?
Phase lock loop is used in analog and digital communications to keep the phase of the output signal the same as the input signal.

Why Positive Feedback can't use in Amplifier?
because +feedback amplify noise also.it amplify the noise to input ratio by[1/(1-G.H)]. WHERE g=open loop gain H=feedback gain
Are there possible ways to find the perimeter of twenty-eight?
Yes.Take a long rope and make a loop so that the length of the rope around the loop is 28 units. Then put it on a flat piece of ground so that the rope does not cross itself. Any shape that it makes has a perimeter of 28 units.Yes.Take a long rope and make a loop so that the length of the rope around the loop is 28 units.
