Req= (R1+R2)//(R3+R4)= 5.2k//1.5k= 1164 x 10^3= 1.2kΩ Rth= Req+R5= 1.2kΩ+1kΩ= 2200 x 10^3= 2.2kΩ Vth= Vs= 9V 16. Derive the Thevenin equivalent of the circuit shown in Figure 7.47b. Req= R1+R2= 22+33= 55Ω Vth= Vs x R3/Req+R3+R4= 12V x 120Ω/55+120+51 = 6.37V Rth= (R1+R2)//(R3+R4)= (22+33)//(120Ω+51Ω)= 41.6Ω 17. Derive the Thevenin equivalent of the circuit shown in Figure 7.48a

our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications of this DC to DC converter is stepping down the voltage. In this experiment a Step down DC to DC

up is very less and be easily supplied by the battery of the vehicle. This fact makes it a very easy circuit to setup. Also‚ as the whole set up is digitalized‚ there is no question of mechanical failure or frequent maintenance. If at all any failure does occur‚ the driver can immediately notice the failure of the circuit as no output value is shown on the display. Hence this is a fail-proof circuit‚ where the driver is always kept informed about the actual fuel levels. What makes this a very attractive
