- Be certain that the students have correctly wired
the voltage sensor parallel to the load and the current
sensor in series with the load.
- As more batteries are added to the light bulb circuit,
advise students to connect the circuit for a couple of seconds.
This will prolong the life of the bulbs.
- There is no need to click start and stop as the voltage
is changed. Students can simply add a battery, close the
circuit, and record the voltage and current values.
