IF an EKG measures electrical signals then how does it record a mechanical process like CPR when there is no electrical signal in the heart?

An EKG measures the sinus rhythm of the heart. Doing CPR will not change the EKG readings. The AED will provide a shock for V-Tach & V-Fib to try to reset the heart so it will regain the normal sinus rhythm

What is the nerve conduction velocity test?
It measures the ability of the nerve to conduct electrical signals
How does a micraphone work?
A microphone is a device that converts acoustical pressure waves (sound) into electrical signals. All microphones have a diaphragm, membrane, or other element in that vibrates sympathetically to the arriving acoustic wave fronts. A sensor in the microphone measures the movement of the vibrating element, and converts the mechanical vibrations into electrical signals. These electrical signals can then be amplified (as in at a concert), transmitted (as in a radio station or telephone), stored (as in a compact disk or MP3), or processed (as in a speech recognition system). For more information, including the different types of microphones, follow the related link below.
What cells contain process that receive and generate electrical signals to communicate with other cells?
the nerve cell.
What is the process called when the ear registers sound waves that are transformed into electrical signals that becomes neural impulses?
We would call that the process of "hearing".
What is metal wire?
Metal wires are single strands of flexible material often used to carry electrical currents, telecommunication signals, and hold mechanical loads.
How does the electronic siren works?
An electric siren is based on the principal of electrical energy and signals being converted into sound. Electrical inputs enter the a speaker through circuitry. In turn these signals are vibrate the air through the speakers function. Electrical sirens are in fact speakers, but there are mechanical sirens which use motion to drive the sound making assembly.
Is it possible to convert microwave signals into electrical signals?
NO
How do the electrical pattern in electronics convey information?
With analog and digital signals.
What instrument measures electrical signals?
The following instruments can all be involved in a measurement of electrical signals, depending on whether the signal is in wire or in the air, and depending on which of its properties and characteristics you want to measure: -- AC voltmeter -- AC ammeter -- power meter -- frequency counter -- field strength meter -- BER counter
How are signals transmitted?
Analog signals are transmitted as electrical waves.
Is fan is an electronic or electrical?
electrical. it does not amplify or modulate signals.
What carries electrical signals that tell the computer what to do?
Control BUSES carries electrical signals that control devices & peripherals in Computers.
