Question

Take the Rrates out and change the ammeter to a current source. R2 R3 source connected to branch 1 (Rs) with the Reat added. Close the switch at position 1. Ra is to be found because lz flows through this branch. The equation of current divider is used. Rrat-500ohms. R1 11T 12 Figure 3: Current source connected to branch 1 (R) with the Rrot added. (other resistors are ommited because no current flows through them in this case). Trat X Rrat R1 + Rrat Given: Rrated-500 and Irated-200A 12-200 Scale current Solving Equation (1) for R1 gives:

Explanation / Answer

Here RRated  is GIVEN & we need to find R1.

So you dont need to find the value of RRated as it would be given or you could choose.

Then by applying the current divison formula, you can find the value of R2.

So you NEED NOT find RRated.
