सिलिकॉन डायोड के निम्न प्रेक्षणों से डायोड प्रतिरोध की गणना कीजिए
V = 0.8 V पर I= 20 mA तथा V = 0.7 V पर I = 10 mA.

(i) i= 0.25 A (ii) V_A - V_B = 3.5 V (iii) V_A - V_C = 2.25 V Equivalent resistance = 7 Omega .

Two batteries V_(1) and V_(2) are connected to three resistors as shown below. If V_(1) = 2V and V_(2) = 0 V, the current I = 3 mA. If V_(1) = 0 V and V_(2) = 4V, the current I = 4mA. Now, if V_(1) = 10 V and V_(2) = 10 V, the current I will be-
