(a) Explanation Given: The given circuit is Calculation: No current will flow through the inverting terminal as the given op-amp is ideal. Therefore, the voltage at the inverting and non-inverting terminal will be the same and equal to zero. The resistance from node 1 will be calculated with the help of below circuit Thus, resistance from node 1 will be R 1 = R The resistance from node 2 will be calculated with the help of below circuit Thus, resistance from node 2 will be R 2 = ( R ∥ R ) + R 2 R 2 = R × R R + R + R 2 R 2 = R 2 + R 2 R 2 = R The resistance from node 3 will be calculated with the help of below circuit Thus, resistance from node 3 will be R 3 = [ ( ( R ∥ R ) + R 2 ) ∥ R ] + R 2 R 3 = [ ( R × R R + R + R 2 ) ∥ R ] + R 2 R 3 = [ ( R 2 + R 2 ) ∥ R ] + R 2 R 3 = [ R ∥ R ] + R 2 R 3 = [ R × R R + R ] + R 2 R 3 = [ R 2 ] + R 2 R 3 = R The resistance from node 4 will be calculated with the help of below circuit (b) To determine The values of currents I 1 , I 2 , I 3 and I 4 (c) To determine The values of currents V 1 , V 2 , V 3 and V 4 .
