A 7.2 V DC motor drives the front wheels of a robot. The motor can draw a maximum current of 1.5A from the source. In order to sense the motor current, you decided to connect a 0.5 resistor in series with the motor. a) Draw a diagram for the circuit showing the voltage source, the sense resistor and the motor b) Calculate how much power the resistor should be able to absorb. c) Calculate the motor voltage if the current through the resistor is 1.5 A. 4
