## Determine the values of load current and output voltage respectively for the below schematic of voltage to current converter with grounded load by assuming that the op-amp is nulled at the inception.

a. 0.3 mA & 4 V

b. 30 mA & 4 V

c. 300 mA & 2V

d. 30 mA & 2V

Correct Answer : a. 0.3 mA & 4 V

**Explanation :**Given data :

From the circuit , the given values are:

V

_{in}= 10 V, R = 30 K & V

_{1} = 2V

We know that load current depends on input voltage resistance R in case of voltage to current converter.

Thus, I

_{L} = V

_{in} / R

= 10 V / 30 K

= 0.3 mA

However, the output voltage (V

_{o}) of voltage to current converter is given by,

V

_{o}= 2 V

_{1} =2 x 2 = 4V.
