কমন-ইমিটার (CE) কনফিগারেশনে, IC এবং VCE এর জন্য লোড লাইন টানা হয়।

F2 S.B 15.9.20 Pallavi D 2

সুতরাং, লোড লাইনের স্থানাঙ্কগুলি হবে:

A = (Vcc, 0) ≡ (+12 V, 0 mA)

\(B = \left( {0,\frac{{{V_{cc}}}}{{{R_c}}}} \right) = \left( {0,\;12\;mA} \right)\)

এখানে,

\(\frac{{{V_{cc}}}}{{{R_c}}} = \frac{{ + 12\;V}}{{1\;k{\rm{\Omega }}}} = \frac{{12\;V}}{{1 \times {{10}^3}{\rm{\Omega }}}}\)

\(= 12 \times {10^{ - 3}}\;A\)

যেহেতু, 1 × 10-3 = 1 মিলি, আমরা লিখতে পারি:

12 × 10-3 A = 12 mA
