What value of resistance must be added to the relay circuit if the relay current has not to exceed 0.02A? Neglect relay resistance.
My idea:
0.02A is the normal threshold for the relay to operate, so under normal operation relay current must not exceed 0.02A. To achieve that balance I would say there is a need for R_S1 and R_L1 (that are identical to R_L2 and R_S2) on the left hand side of the upper line. If that's the case how do I calculate them?
Thank you anyone's effort to look into that.
