3. If a photodiode were to be used as a sensor, at what point should the anode be? +Vcc R1 SR2 1MO 1k2 Opamp VOUT A R4. R3 1kn Ov b point a point b 9. Why is R4 variable? O to vary the voltage equivalent of light detected Oto vary the output of the op amp to vary the possible reference voltage equivalent of light detected to vary the bias of the op amp

KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.
