Relaxation Oscilator used in 1. Blinking lights 2. Inverters which produce low frequency signals.

1. The ideal transformer is a model of transformer with a coupling coefficient equal to unity(1). 2. The operation of ideal transformer is the same in the time domain as in the frequency domain.

Yes. (Learnpick Admin, I hope you are literate and technically sound enoough to understand this question. My answer is precise. Student is checking if he can use Raspberry Pi or not. Please do not reject my answer. Please reject question. Thanks)

An Alternating Current Voltage is one in which the value of either the voltage or the current varies about a particular mean value and reverses direction periodically.

The path for the flow of alternating current is called an AC Circuit

Permeability is a constant of proportionality that exists between magnetic induction and magnetic field intensity. This constant is equal to approximately 1.257 x 10-6 henry per meter (H/m) in free space (a vacuum). In other materials it can be much different, often substantially greater than the free-space value, which is symbolized µo

You can calculate it by calculating current in the circuit, resistance of each bulb and then adding power in each bulb by i^2R Alternatively Total power=200*200/400=100W

ADC is an Analog to digital converter which converts the varying Analog signals into digital signal

In parallel connection, the formula to calculate n resistance is 1/R= 1/R1 +1/R2 +......+1/Rn When 2 resistance are connected in parallel the net equivalent resistance will be smaller. Let us take an example: R1 =10( larger resistance ) R2=5( smaller resistance) Equivalent resistance R=(R1*R2)/R1+R2) =50/15 = 3.33 ohm (which is less than R2)

Motor controller is circuit witch is use to control motor speed and starting current.
