To balance the input currents.Why a resistor is connected between non inverting terminal and ground.

The output is the difference between - and + inputs multiplied by the gain of the inverting amplifier. If there is NO connection to + input, then there is no way for the amplifier to reference the difference between the inputs. Note, the + input can be connected to other voltages and the output will change based on the gain and difference between the two inputs.Why a resistor is connected between non inverting terminal and ground.
