Electronics Engineering

An ammeter is used to measure the intensity of current flow in a circuit or branch in a circuit. It is wired in series with the circuit being evaluated to accurately measure the current passing through that specific part of the circuit.

104VAC is the highest voltage less than 115VAC minus 10%, which is 104.5VAC. 127VAC is the lowest voltage greater than 115VAC plus 10%, which is 126.5VAC. Plus or minus 10% is considered to be the design basis range of standard 115VAC equipment, in order to maintain correct operation.

A closed circuit is one where the current is flowing continuously from the source to the load and back to the source, completing a loop. An open circuit, on the other hand, is one where the current cannot flow because the circuit is broken at some point.

One statvolt is about 300 volts. (299.792458)

Total internal reflection occurs when the incident angle is greater than the critical angle, causing light to be reflected back inside the medium rather than refracting out of it. This phenomenon is commonly seen in prisms and optical fibers.

Yes, but the impact depends on the frequency and type of antenna. It's mainly the effect of free water absorbing the RF energy.

Low frequency near field systems have very little problem with water, while higher frequency far field systems can be completely stopped by wet leaves or free water.

copper oxide is a semiconductor. it used to be used for power rectifiers.

The flow of electrons is called electric current. It is the movement of electric charge through a conductor, such as a wire, in response to an electric field.

1. Voltmeter has high impedance and hence will restrict the current severely.
a) Electric Bulb will not glow
b) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.
c) The Voltmeter will measure the Voltage that is being applied.
d) This will allow you to measure the resistance of the Voltmeter.

VR=V/I

For a current to flow there must be a voltage, and a conductor through which the current can pass.

There are a few variables to take into account here. The discharged state of the battery and the current produced by the battery charger on the slow charge position are two of the most important. The amp/hour size of the battery is another governing factor.

There are no rays assign as anode rays (cathode rays are there in a discharge tube) but during discharge tube experiment positive rays are observed which are generated by decomposition of gaseous molecules present in the tube. X-rays are produced by striking of cathode rays with anode so x-rays may be called as anode rays.

As methane belongs to the group alkane compounds which do not contain C=C double bond therefore is saturated and not easily reacting with other molecules.

A: All current in a loop must return to the source. A source may feed many loops but all these loops current will return to the source as a collective.

Series Circuit

The load of a flashlight circuit is the component that consumes electrical power, typically an LED bulb or an incandescent bulb. The load transforms electrical energy into light energy to illuminate the flashlight. It is an essential part of the circuit that determines the brightness and performance of the flashlight.

If you connect a 100 ohm resistor across 120 volts it will draw 1.2 amps, amps = E/R. Power = volts x amps so the power required for the resistor would be 120 x 1.2 = 144 watts.

It would not matter if the 120 volt circuit already has 2 amps load on it by something else to calculate the wattage of the resistor.

The total power on this circuit would be the 144 watts from the resistor and 240 watts from the other 2 amp load (2a x 120v) for a total of 384 watts.

If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance

when no electricity flow then chare are in condition of static

initially the two beams i.e. one reflected and one transmitted from semi reflecting glass were in different phase but when they superimpose two interference take place - constructive and destructive. since in both the interferences amplitude changes.

A 4-20ma current loop is often used in process control and monitoring systems to signal a value from one point to another. It operates using Kirchoff's current law, in that the transmitter can monitor the current on the loop, knowing that will be the same current at the receiver. Any deviations in reference voltage or ground differentials between transmitter and receiver can then be compensated for at the transmitter. The signal range starts at 4ma, so that the receiver can detect the 0ma condition representing a break in the wire.

You can also have multiple receivers on the loop, all in series, so long as the delta voltage at each receiver does not contribute too much voltage to the overall loop. Each receiver will see the same current, again due to Kirchoff's current law.

A cathode ray consists of a stream of electrons generated by heating a cathode. These electrons are accelerated and focused by electric and magnetic fields before hitting a phosphorescent screen to produce a visible image.

Igneous rocks are classified as rocks that originated from the liquid phase, specifically from the cooling and solidification of magma or lava.

That depends on several factors that aren't specified in the question:

-- whether the resistors are connected to each other

-- whether they're connected in series or in parallel

-- the voltage applied across the ends of the circuit

While these two resistors are in their plastic packages hanging on the wall at Radio Shack,

the total current flowing through both of them is zero.

Electrons were produced in a cathode ray tube by applying a high voltage to the cathode, causing electrons to be emitted through thermionic emission. These electrons were then accelerated towards the anode by the electric field within the tube, creating a beam of electrons known as the cathode ray.
