- Yesterday, 22:43Everything seems to be correct except the RL load current. The Ammeter and Current Graph are showing 23A and 26A(peak). R is 10k and L is 36mH....82 replies | 979 view(s)
- Yesterday, 17:13Long back I studied electronics but did not study analog electronics much because it was full of equations. You cave i(theta) or i(t) formula....82 replies | 979 view(s)
- Yesterday, 15:57Why you say source is not DC. I am giving rectified dc to RL load. The voltage doesn't have negative half wave and hence it is not alternating...82 replies | 979 view(s)
- Yesterday, 15:38Ok. I will try but why my calculation is wrong ? In RL series circuit the current will be max at 5 * tau and if I assume it to be 50mA then...82 replies | 979 view(s)
- Yesterday, 14:30FvM and CataM I need to get graph as in post 75. Please solve this equation to get the value of R using math software. When R/L = 5t the...82 replies | 979 view(s)
- Yesterday, 12:16@FvM and CataM Please provide a quick solution for RL Load values. See attached simulation result. Only these RL values are giving the required...82 replies | 979 view(s)
- Yesterday, 06:11I am having a small problem. If I use R load then firing angle is varying but if I use RL load then firing angle is not varying. Why ? I don't...82 replies | 979 view(s)
- 27th March 2017, 18:54Yes CataM give voltage which will be like 230V simulation signal for 24V AC. CataM, XL - omegaL = 2*pi*f*L We are feeding pulsated dc to RL...82 replies | 979 view(s)
- 27th March 2017, 10:24I am using 24V AC for SCR circuit and also for power supply. A 220V / 24V transformer is used. A LM317T provides 5V from 34V rectified voltage....82 replies | 979 view(s)
- 27th March 2017, 01:01I am getting this. This is giving some backemf but not 28V. How can this be improved ? phi = arctan(VL/VR) I = -100mA (assumed) Phi = 20...82 replies | 979 view(s)
- 26th March 2017, 19:59I am really sorry. I did wrong calculation. What I want is this. V = VR + VL = IR + IXL XL = 2 * pi * f * L f = 50 Hz L can be assumed as...82 replies | 979 view(s)
- 26th March 2017, 19:04Thank you for the circuit. I will check it. Can you tell how you designed it ? Which simulator you used ? Cadence OrCAD PSpice ? I am not getting...82 replies | 979 view(s)
- 26th March 2017, 17:07In Series RL Circuit Analysis section strp III here https://www.electrical4u.com/rl-series-circuit/ I got the formula but for phi = 55.83...82 replies | 979 view(s)

- 26th March 2017, 16:31@CataM tau = L/R but without knowing L and R how can I calculate tau ?82 replies | 979 view(s)
- 26th March 2017, 15:46@FvM If 24V AC is converted to dc then it becomes apprx 39V. How you got 34V ? Vpk = Vrms * 1.4142 How you got 34V ? If you meant 39V then...82 replies | 979 view(s)
- 26th March 2017, 14:43@CataM Yes, I want it to perform like in the referred document that is ijsrp_p4937.pdf but for 24V AC. 1. I will choose max conduction angle...82 replies | 979 view(s)
- 26th March 2017, 13:36What is the difference between why I want an inductive load and reasoning. My client has to show the waveforms for RL load where negative voltage...82 replies | 979 view(s)
- 26th March 2017, 13:03I convinced my client to use 24V transformer and a LM317T to get 5V DC for PIC circuit. 1A bridge is used and also to use 24V AC from transformer...82 replies | 979 view(s)
- 25th March 2017, 22:35Okada replied to a thread Arduino UNO unsure about coding for project, help appreciated!! in MicrocontrollersI am not sure about it. I have never used such a code. I have done practical adc reading using arduino and it gives me correct values. It gives 0V =...28 replies | 505 view(s)
- 25th March 2017, 22:18The circuit mentioned that document doesn't simulate in Proteus and thats why I made a separate simulation circuit. The simulation and practical...82 replies | 979 view(s)
- 25th March 2017, 21:39L/R = 4.69 * 10^-3 V = 240V If R = 100R then L = 100 * 4.69 * 10^-3 = 469mH but if I choose lower reistance then how it will handle high...82 replies | 979 view(s)
- 25th March 2017, 21:20For MOC3021 input circuit I have choosen 220E resistor. I took Vf = 1.15, If = 20mA, v = 5V So, (V - Vf) / If = (5 - 1.15) / 20mA = 192.5 ...82 replies | 979 view(s)
