This lab will require a power supply but what kind of power supply? This will be very important to the lab as the wrong power supply setting means a correctly assembled circuit will not work. (Note: depending on the edition of the lab manual this information can be found in the Basic Measurement or Simple Circuit lab write-ups.)

The energy released by a nuclear fusion reaction is produced when

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
