Electronics Engineering

Technically no, it'll always cause the same amount of damage to your body, but it will fry your nerves, making you more immune to the pain of it. Electricians are normally quite used to the pain and side effects.

The type of connection with two or more components where there is only one path for current flow is known as a series circuit. In a series circuit, the components are connected end-to-end, so the same current flows through each component. If one component fails or is disconnected, the entire circuit is broken, stopping the flow of current. This configuration is often used in applications where the same current must pass through all components.

When 60 hertz current is used, current flows in one direction for half a second. This is because for 60 Hz frequency, polarity changes 60 times in a second, meaning it flows in either direction for 500 Ms.

the capacitor and its associated resistor set the time constant.

depletion region is formed only after recombination of holes and electrons..so in depletion region there are only and only immoble positive and nagative ions...hence,there is no charge carrier..

The gain of an op amp varies with frequency. After an op amp reaches the half-power point, the gain falls appreciably. And then once it hits the transition frequency, the op amp no longer provides any gain.

A resistor is a material that attenuates the current through a conductor. An insulator isolates the conductor from the surrounding material.

When a signal of 10 mV at 75 MHz is to be measured then which of the following instrument can be used -

A power inverter converts DC to AC , if you trying to build a power inverter then you need power invert circuit schematics.

There are some kind of specific inverters with the help of which you can easily convert DC power into AC power. In a solar electric system we generally receive sun rays in photovoltaic cells which contain silicon as a mechanical material. This mechanical material converts solar energy into DC power. This DC power is then redirected to a inverter which converts it into AC power and we restored this AC power into solar batteries.

The v in vdc stands for volts. The dc stands for direct current. This is a voltage that you find in batteries and is not to be confused with AC which is alternating current which is the electricity in the utility grid that feeds your home electricity.

it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.

RF Code first began offering products in the 303MHz range (US & Japan) and later in the 433MHz range (US & Europe). These signal frequencies are limited, low-power, unlicensed ranges in the ISM (Industrial, Scientific and Medical) portion of the UHF band. RF Code began offering 433MHz products because of acceptance of this frequency in Europe. 433MHz is also the frequency which offers optimal performance in crowded environments such as offices, data centers, and hospitals.

Generally, radio signals at lower frequencies travel farther than those at higher frequencies. Lower frequencies also benefit more from the effects of reflection and refraction which makes them more suitable for applications in crowded environments. For example, the 433MHz wavelength is approximately 69 cm vs. 10 cm for 2.4GHz. The larger wavelength of the 433MHz signal allows it to diffract around obstructions that might be found in a typical, crowded operating environment such as an office or warehouse. At frequencies of 2.4GHz and above, the signal is susceptible to obstructions, creating blind spots (areas of no coverage). Higher frequencies also require more power.

A highly conductive metal is one where the availability of electron flow is high. Examples are copper, silver, aluminum, etc.

You have not provided enough information. For 12 volt peak to peak, purely AC signal, there will be no DC (hence purely AC). This means there is no offset - the AC signal peaks at 6 volts and -6 volts. The RMS value of this is VRMS = peak / sqrt(2) = 6 / 1.4.

Diodes are rated to use a certain amount of current. If you go over that amount, it will eventually destroy the device, how long it takes to destroy the device depends on how much more current you are running through it than it is rated at.

Organic semiconductors are inexpensive hence easy to fabricate device out of them, they can be modulated in various desirable way like in electronic properties of band gap, can be made transparent which is good for Optical electrodes, flexible. Because of these modulation they are finding their application in wide varieties of area. Of course they are very attractive choice for researchers now a days.

The correct statement of Ohm's Law can be written as:

R = V/ I

Where R is resistance

V is the potential difference.

I is the current.

he circuit works off a 9V regulated power supply. However, battery back-up is recommended. A common-cathode, 7-segment display (LTS543) is used for displaying whether the loops are intact or not.

If loop 1 is broken, the display will show '1'. If two or all the three loops are broken, the display will show the sum of the respective broken loop nently. The loops are also connected to a dual 3-input NOR gate and inverter CD4000 (IC2) to activate the alarm.

Fig. 1 shows the circuit of the digital security system, while Fig. 2 shows the proposed wiring diagram for the loops around the premises. Before using this security system, make sure that loops shown in Fig. 2 are connected as shown in Fig. 1. If you don't want to use a buzzer, switch it off by opening switch S2.

The circuit works off a 9V regulated power supply. However, battery back-up is recommended. A common-cathode, 7-segment display (LTS543) is used for displaying whether the loops are intact or not.

If loop 1 is broken, the display will show '1'. If two or all the three loops are broken, the display will show the sum of the respective broken loop numbers. For example, if loops 1 and 4 are broken, the display will show 5(1+4).

When all the three loops are intact, the display will show '0.' All the three inputs of gate N1 remain low to give a high output. This high output is further given to gate N2 and, as a result, its output remains low. This keeps transistor T1 in cut-off position and the piezobuzzer does not sound.

When any loop is broken, the output of NOR gate N1 goes low, while the output of gate N2 goes high. Transistor T1 conducts and the buzzer sounds to alert you. You can mute the buzzer by switching off power to the circuit through switch S1.

An intrinsic reward is simply a mental feeling of achievement or accomplishment that has no physical representation. I.E. a simple "well done" from a co-worker. This is as opposed to extrinsic rewards such as physical certificates or medals.

A change in frequency of the motor will cause a change in the speed of the AC conveyor motor. This frequency change is brought about by a device called a Variable Frequency Drive. It is used to vary the frequency of the motor from 0 to 100%. I have no idea what the second answer is talking about.

ANSWER: considering that no mention of type of motor is involved the frequency change theory is quite invalid since 50 or 60 Hz AC line runs clocks from banks to wake up calls and while it is true that the frequency is not accurate from second to second it is however very accurate from minutes to minutes.

The maximum transmission speed for fiber optic is about 186000 miles per second. Wires are a bit slower because of transmission line effects
