Which is an example of current electricity?
Electrical current is the measure of the flow of electrons, measured in Amperes (Amps). An example would be to compare it with a fluid flow meter. As opposed to pressure, which is analogous to Voltage.
What is used to measure moonquakes?
A seismometer would measure earthquakes, but there is no such activity on the moon to measure.
What is a measure of how often you perform an activity?
frequency
What does the pH of a dilution measure?
pH is a measure of the hydrogen ion (H+) activity in a solution.
How many electrons does magnetism have?
Magnetism and Electricity are two totally different things . Electricity is the movement of electrons in an electrical conductor (usually Copper or Aluminium) Magnetism exists as a stationary force field surrounding a magnet which has all of the stationary electrons in the magnetic material, all pointing in the same direction. Electrons cannot be counted and nobody has any need to count them. (Just as we have no need to count the quantity of molecules in a stream of water in a pipe.) We only measure the EFFECT of electrons when they flow in a wire. it is called 'Current". With magnetism we measure the strength of a magnetic field, which is a stationary thing . Field strength is measured in 'Oersted'.
What does ECG measure?
The electrical activity of the heart.
What is the medical term meaning instrument to measure the electrical activity of the brain?
The medical term is electroencephalograph (EEG), which is a device used to measure the electrical activity of the brain.
What measure of electrical energy transfers by electrons in a circuit?
Voltage
What does an electrocardiogram measure?
The electrical activity of the heart over time.
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
What is a cardiograph?
A cardiograph is an instrument designed to measure and record the electrical activity of the heart.
What is the difference between an MRI and a EEG?
Both measure electrical activity -- the ECG in the heart and the EEG in the brain.An EEG is an electroencephalogram and an ECG also known as an EKG is an electrocardiogram. An EEG records brainwave/electrical activity. An ECG records the electrical activity that the heart produces.
Does an electrocardiogram record the electrical activity of the heart?
Yeah, that's its prime objective. The leads placed on the limbs can measure the heart's electrical activity, as the voltages generated in the heart are readily transmitted through the body to the limbs.
What does volt measure?
Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.
Is a measure of how often you perform an activity?
The measure of how often you perform an activity is the frequency.
Which is the unit of measure they describes electrical pressure is?
Volt is a measure of electrical pressure.
Is an electrocardiogram a noun?
Yes, the word 'electrocardiogram' is a noun, a word for the record or display of a device used to measure electrical activity of heart muscles; a word for a thing.
