Hello,I find difficult solving this problem.   This problem is to find the equivalent resistance between node A and node B when (a) node C and node D is shorted          (b) node E and node F  is shortedThank you for solving this problem.

(c) Design an Aryton shunt meter as shown in Figure Q1 (c) to provide an ammeter with a current range of 0-1 mA, 0-10 mA, 0-50 mA, 0-100 mA. Given Im= 50 µA and Rm = 100 Q 1mA R4 10mA R3 50mA D'Arsonval movement R2 100mA R Figure Q1 (c)

How do I do questions 1 and 3
