Do you have to turn off electricity to change a doorbell?
Yes, the wire attached to the doorbell does carry an electric current and you can get a shock if you work on it without turning off the power first. Ideally, you should locate the specific fuse or circuit breaker for that particular wire, so you don't have to turn off all the power to the whole house. Be careful; electric shock can be very dangerous.
Which type of device emits a sound wave?
First you convert the sound into a modulated electric current using a microphone, then you convert the modulated electric current into a visible pattern using an oscilloscope.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What does the electric current have?
In metal conductors, electric current is the flow of electrons.
What kind of electric current does an electric stove use?
An electric stove uses Alternating Current to operate.
What is the defense mechanism of a electric eel?
Electric eels send a electric current through the water to stun their attacker.
How do electromagnet get their names?
An electromagnet is only magnetic when an electric current is run through it.
What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
In electric bell electric energy is converted into?
An electric doorbell uses electrical current thru a coil to move a metal bar using magnetism and cause it to strike a metal plate making a ring sound
What makes the pickup guitar make sound?
A guitar pickup is wire coiled around a magnet. When the string vibrates, it causes the magnet to vibrate, which creates an electric current in the wire. The signal created by that electric current is then fed into the amplifier which converts it to sound.

What can you do to conserve energy?
You can perform reversible Work: stretching a spring - you can look at some old watches and see the mechanism. you can put electric current into a Capacitor.

What are some common objects that use solenoids?
A solenoid is a cylindrical coil of wire that acts like a magnet when carrying an electrical current. Solenoids are used in railroads and car starters, acting as an electric switch. They also control water flow in washing machines and dishwashers. Also a TV, and a doorbell, by pushing the coil behind the button to sound the doorbell.
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
What is the direction of flow of electric current in an electric current?
DC current
Can an electric bell work on an ac supply?
Is it a doorbell? What do you need the bell for? The type of bell determines what source of electricity is used. Once you determine the type of bell it is, you can hook it up to the right circuit. I had to install a doorbell that worked off the AC current. I also installed one that contained a battery. When you say electric bell, you need to clarify what type of bell it is so a more accurate answer can be given, especially if the answer I provided above it not accurate for you. Thanks for your question.
