3) As part of Huawei's electrical engineering team, you have been tasked to participate in the design of their new phone.
a) Two electrical components in the phone have to be able to send signals to each other.
One of your colleagues is suggesting that a single conductor be placed between the
components for communication. Another colleague suggests that three conductors be
placed between the components. Your manager comes to you for your views on the
matter. In less than 10 lines, explain what each approach implies and list their
advantages and disadvantages. (10 marks)
b) A very sensitive sensor, which requires 0.5 A is to be placed at a particular point in the
phone. The current flowing through that point is 2A. In less than 5 lines, explain how
you will ensure that the sensor is supplied with 0.5A as required for safe operation

c) What is likely to happen if 2A is passed through the sensor? ( marks)
