An mbed is part of a circuit which is to be powered from a 9-V battery. After programming, the mbed is disconnected from the USB. One part of the circuit external to

the mbed needs to be supplied from 9 V and another part from 3.3 V. No other battery

or power supply is to be used. Draw a diagram which shows how these power connections should be made.
