Have a question on electrical protective devises!!? Best Answer: A. GFCI is the correct answer. Ground Fault Circuit Interruptor: This will open the circuit when a difference in current is detected between the hot and neutral wires in a 120VAC (House current) circuit. B Circuit Breaker will only open the circuit on the hot side when a maximum current is reached. C. Blows open when a maximum current is reached in one line.

The Basics of Current Sensors Current sensors are either open-or closed-loop. Open-loop current sensors measure AC and DC currents and provide electrical isolation between the circuit being measured and the output of the sensor (the primary current is measured without electrical contact with the primary circuit, providing galvanic isolation).

Electrometer An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. There are many different types, ranging from historical handmade mechanical instruments to high-precision electronic devices.alves designed for electrometer use have leakage currents as low as a few femtoamperes (10 −15 amperes). Such valves must be handled with gloved hands as the salts left on the glass envelope can provide leakage paths for these tiny currents.

Voltmeter Design A voltmeter is placed in parallel with a circuit element to measure the voltage drop across it and must be designed to draw very little current from the circuit so that it does not appreciably change the circuit it is measuring. To accomplish this, a large resistor is placed in series with the galvanometer. voltmeter is placed in parallel with a circuit element to measure the voltage drop across it and must be designed to draw very little current from the circuit so that it does not appreciably change the circuit it is measuring.

- Common usage refers to a potential difference relative to ground (0.0 V) as simply the voltage, though it is prudent to call it by its correct name to emphasize the way it is measured. The potential difference across a circuit element is measured by placing the two leads of a voltmeter on the two sides of the element. Its removal will not change the circuit.” (http://www.physics.udel.edu/~watson/phys345/lab/meters.html)

Galvanic Isolation: Purpose and Methodologies Hall Effect Sensor. Another method of passing information between electrical systems with separate ground potentials is the use of a Hall effect sensor. A Hall effect Sensor detects inductance non-invasively and does not require direct contact with the signal in question and does not violate the isolation barrier.

galvanometer Although the deflection of a galvanometer results from current in the moving coil, the voltage in a closed circuit producing this current is frequently the quantity of interest to the user. In this mode, galvanometers are used to detect a null or an unbalanced condition in a bridge or potentiometer circuit.he current through the galvanometer (and hence the pointer reading) is then proportional to the voltage (see Ohm's law Ohm's law[for G. S. Ohm], law stating that the electric current i flowing through a given resistance r is equal to the applied voltage v divided by the resistance, or i=v/r......

ACS712: Fully Integrated, Hall-Effect-Based Linear Current Sensor IC with 2.1 kVRMS Voltage Isolation and a Low-Resistance Current Conductor The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer.

- The LDR. LDRs (light-dependent resistors) are used to detect light levels, for example, in automatic security lights. Their resistance decreases as the light intensity increases: LDR symbol. 1  In the dark and at low light levels, the resistance of an LDR is high, and little current can flow through it.2  In bright light, the resistance of an LDR is low, and more current can flow through it. In the dark and at low light levels, the resistance of an LDR is high, and little current can flow through it.

Electrochemistry Basics In this case, the anode has a higher potential energy; electrons therefore move from anode to cathode. The potential difference between the two electrodes is measured in units of volts. One volt (V) is the potential difference necessary to generate a charge of 1 coulomb (C) from 1 joule (J) of energy.

Integrated circuit A barrier forms along the boundary between p-type and n-type semiconductors that is known as a p-n junction. Because electrons under ordinary conditions will flow in only one direction through such barriers, p-n junctions form the basis for creating electronic rectifiers and switches.

Galvanometer A tangent galvanometer is an early measuring instrument used for the measurement of electric current. It works by using a compass needle to compare a magnetic field generated by the unknown current to the magnetic field of the Earth.hen an electric current flows through the galvanometer coil, a second magnetic field B is created. At the center of the coil, where the compass needle is located, the coil's field is perpendicular to the plane of the coil. The magnitude of the coil's field is:

Electric Current The convention has stuck and is still used today. The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
