M 4 2- (25) Find I, 3213 'C 20v 212 2 212 go 2

find I1

Answer 1

The property of Current is that, it looks for low resistive or shorted path to flow through it. Here, current I1 finds shorted path to flow. Hence effective resistance of the source is 0 ohm. So current I1=20/0=infinite

Solution of 2.2 DI V 20 V gon m 22 2. > from pesume di and De are cdeal. from above above circuit, we can noticed that diode Di is forward biased and diode Dz is reverse beased. above circuit reduced to, ti The a بو sqar + سام 20v b ta . Mhe 202 2.2 la a from above circuit, Current finds shorted path to flow. it 201 I a here, Effective resistance is zero. (very large) 20 20 So, ll fis B

Therefore, Current flows through the circuit is very very large or infinite.
