Section A

Q1.

(a) चित्र 1(a) में दर्शाए गए नेटवर्क में निम्नलिखित को ज्ञात कीजिए:
(i) अधिकतम शक्ति स्थानांतरण हेतु लोड प्रतिरोध की मात्रा
(ii) लोड को प्रदत्त अधिकतम शक्ति की मात्रा

In the network shown in Figure 1(a), determine the following:
(i) The value of the load resistance to have maximum power transfer
(ii) The maximum power delivered to the load

(b) दो विस्तृत रूप से समरूप समदैशिक परावैद्युत (डाइइलेक्ट्रिक्स) एक समतल z = 0 पर मिलते हैं । जब z > 0 है, तो arepsilon_{r1} = 4 है और जब z < 0 है, तो arepsilon_{r2} = 3 है । एक एकसमान विद्युत्-क्षेत्र overrightarrow{E}_1 = 5hat{a}_x - 2hat{a}_y + 3hat{a}_z kV/m, z ge 0 क्षेत्र में विद्यमान है । ज्ञात कीजिए:
(i) z le 0 क्षेत्र में overrightarrow{E}_2
(ii) दोनों परावैद्युतों में ऊर्जा का घनत्व (J/m3 में)

Two isotropically homogeneous dielectric materials with arepsilon_{r1} = 4 for z > 0 and arepsilon_{r2} = 3 for z < 0 meet at the plane z = 0. A uniform electric field overrightarrow{E}_1 = 5hat{a}_x - 2hat{a}_y + 3hat{a}_z kV/m exists in the region z ge 0. Determine:
(i) overrightarrow{E}_2 in the region z le 0
(ii) The energy density (in J/m3) in both dielectrics.
