What does radar measures?
It measures the time it takes for a radio signal of a particular frequency to travel to a target and back. It also measures the strength of the signal when it returns. Based on the travel time of the signal, the radar can measure the distance of the target. Once the radar receives the 2nd signal, it can calculate the velocity of the target. The strength of the signal can be used to determine the size of the target.
What does the phase of a signal measure?
•Measures each point in a single cycle of a signal relative to its point of originPhase tells you the delay in a signal
What is one different between a galvanometer and an electric motor?
Electric motor is a machine that converts electrical energy to mechanical energy while a Galvanometer is an electrical instrument that measures small values of current.
What is ammeter used for?
An ammeter measures the electrical current in something. A digital one is calibrated to display through the shunt and convert information from the analog model.
How voltmeter works?
It is connected in parallel and measures potential difference.
Can electric give of a signal near a steel pipe with no electric in it?
You could be getting a signal from a tracer wire.
Effects of the electric resistance on a signal?
Weak signal depending upon the type of signal.
What instrument measures the electric equipotential?
Multimeter is an instrument that measures electric equipotential. Equipotential lines can be determined by connecting various points of electric potential or voltage.
