Best Practices in IPD Team Meetings
1. Team meetings should be scheduled at a time all members can attend and it should be held at
the same time and place each week.
2. Attendance should be taken at all meetings and notation should be made if anyone is la

What is a Wheatstone Bridge?
It is a configuration of resistors and a galvanometer (ammeter) that was eventually named after
an Englishman, Charles Wheatstone; hence the name. The Wheatstone Bridge configuration is
