A coil connected across a d.c. supply will cause a spark to occur across a switch when turned off. The current flowing in the circuit at this moment is given by the equation i = IetR/L amps. Where I is the maximum circuit current, R the resistance of the coil and L the inductance of the coil...

A capacitor and resistor are connected as shown across a 10V d.c. supply. The voltage across the capacitor will increase at an exponential rate given by the equation v = V - Vet/CR a) Plot the graph of the capacitor voltage from the equation for values of t between 0 and 24 seconds. vc = V...

^^ yes, you guys are absolutely right & my mistake I wasn't doing in rad. it is equal to 6 then the amplitude would be 6 - (-6) / 2 = 6

why have you taken sin of half pi? I still didn't get it.

i have done it in rads only. & how can it's be 1?

i think maximum value of sin is 6 but i don't know what's it implying on the amplitude of 6sin.

v = 6sin (314t + π/2) v = 6sin (314(0) + 3.14 /2) v = 6sin (0 + 1.57) v = 6sin(1.57) v = 0.16 v = 6sin (314t + π/2) v = 6sin (314(0.01) + 3.14 /2) v = 6sin (3.14 + 1.57) v = 6sin(4.71) v = 0.49 v = 6sin (314t + π/2) v = 6sin (314(0.02) + 3.14 /2) v = 6sin (6.28 + 1.57) v = 6sin(7.85) v = 0.81...

Verify the compound angle formulae for; a) sin (20° + 30°) sin(A + B) = sinAcosB + cosAsinB sin(20°+30°) = (sin20°)(cos30°) + (cos20°)(sin30°) 0.76 = (0.34 x 0.87) + (0.94 x 0.5) 0.76 = 0.29+0.47 0.76 = 0.76 b) cos (30° + 40°) cos(A + B)...

A sinusoidal voltage is represented by the formula v = 6sin (314t + pi/2). Sketch the graph on the graph paper provided for values of t from 0.0s to 0.04s and show on the graph the values of • the amplitude • the time period and show how the frequency of the waveform may be determined from...

I have finally managed to get it work and it’s all because of your help and support. I really appreciate your hard work and hope you will continue to help guyz like me in the future too.

someone suggested me these ideas; But for this I need circuit diagrams as I am having difficulty in connecting this circuit in multisim. In this one i am lost in which rectifier to go for as there are many but I need one which can work on 12v & I need a circuit diagram for this one (please...

^^ Can I have a circuit diagram please? As I am finding it very hard to draw on multisim.

I want buzzer to sound when the headlights are on and engine is off. And when the engine and headlights both are on; nothing should happen.

Hello Guyz! First of all I am new here and I found this section to be appropriated for submitting my question. Well, I was Investigating on Car headlight Alarm and how it should sound a buzzer when the headlights are on? I have attached the circuit diagram as well you might want to have...
