Question

VDD 24V R2 X1 10MO Key A 30V 10W 50 % Q1 IRF250 R1 1MO 2. Add 3 voltmeters to measure VG, VD, and Vx1. Run the simulation. (The lamp should be off. If not adjust R2 until the lamp is off.) 3. Measure the values listed in Table 6 with the lamp off 4. Adjust R2 until the lamp comes on. 5. Measure the values listed in Table 6 with the lamp on. Table 6 Measured Parameter Values VD off VG off VX1 off VD on VG on Vx1 on 6. What is the minimum value of VGrequired to turn on the lamp?

Answer 1

Here is the simulation and the value of voltages when the lamp is off

x Multimeter-XMM3 lamp off 2.164 mV хммЗ V C dB х1. Set... R3 Multimeter-XMM1 30V S10MQ 45 % 2 Key A 3.689 XMM2 хмм1 v dB A V1 _ Q1 24V IRF250 Set R1 Multimeter-XMM2 1MD 23.998 V V dE Set..

And here is the simulation when the lamp is on

2 3 4 7 LAMP ON Multimeter-XMM2 23.291 V XMM2 dB V X1 Multimeter-XMM1 V1 R1 30V Set... 24V 4.36 V 10MO Key A 55% v A XMM3 Set... Q1 XMM1 IRF250 R2 >1MO Multimeter-XMM3 110.011 mV dB V Design1 * Set...

Here is the complete table

VD off	23.99V
VG off	3.689V
VX1 off	2.164mV
VD on	110.011mV
VG on	4.36V
VX1 on	23.29V

6, Minimum value of VG required to turn on the LAMP is 4V

Please thumbs up.
