Question

a constant current source supplies a electric of 200 mA to a load of 2k . when the load changer to 500 .the load current will be
1- 9 mA
2- 8A
3- 700mA
4- 12A

Answer 1

Answer:

I think b

Explanation:

Answer 2

Given-

Current 1- $200 mA$

Resistance-$2k$

Resistance -$500$

To Find-

Load current

Solution-

The voltage for the initial condition is V=IR (Ohms Law)

V=  $200 mA$×$2k$

V= $4000 V$

Now, the V= $4000 V$, Resistance = $500$

So, the current is V/R

Current is  $4000 V$/ $500$

Current is $8 A$.

Hence, the correct load current is 8 A.
