Refer to Figure 5 (image attached) : Why does LED turned on quickly and turned off gradually, when there is a 47uF capacitor placed in the circuit ? What will happen when 47uF capacitor will be replaced by 470uF capacitor?Also tell, what difference do you observe when there is no capacitor in the circuit?

177. Describe the principles behind electrochemical capacitors (supercapacitors) and their advantages and limitations compared to conventional batteries in energy storage applications.

The waveform displayed on an oscilloscope is as shown in Figure The 'time/cm' switch is set to 10 ms/cm, and the 'volts/cm' switch is set to 50 V/cm. Determine the (i) amplitude of waveform Q, (ii) peak to peak value of waveform P, (iii) frequency of waveform P and (iv) phase angle difference between P and Q in Degrees. Q
