Inductor impedance is given by jwL, where w=2*pi*frequency. Therefore as the frequency increases the impedance of the inductor increases, causing a larger current flow and a larger power dissipation across the inductor

My mobile phone (an Alcatel) charger will supply 500 mA at 5 V. So the maximum continuous power it is capable of supplying will be the product of these two -i.e. 2.5 W. Of course, it won't necessarily ever reach that value in practise.

The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.

There's no such thing as a 'negative voltage' in the 'polarity' sense, only in the 'direction' sense. So what exactly are you asking?

Light may be generated in two conditions.

a) when a material is heated sufficiently that it glows - so-called black-body radiation,

b) when an excited electron; previously raised to a higher energy level than its natural state; is allowed to cool and return to its natural energy level.

In this energy shift, it will emit a quantum of light quite specific to the element concerned, and the energy change.

If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.

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.

The FCC has set-aside certain frequencies for certain uses. Some frequencies require licenses and others are allowed to operate unlicensed if they meet certain parameters (usually power level and type of transmission). 433.92 Mhz has obviously been set-aside for unlicensed use for low power data transmissions, which is why so many devices use that frequency for that purpose.

Does not matter!

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