... Noncontact mode belongs to a family of AC modes, which refers to the use of an oscillating cantilever. A stiff cantilever is oscillated in the attractive regime, meaning that the tip is quite close to the sample, but not Touching it (hence, “noncontact”). The forces between the tip and sample are qu ...

... This was a 33 W resistor connected to a 20 V supply. The current would be 20 V ÷ 33 W = 0.61 A The power would be 0.61 × 20 V = 12 watts. Plenty enough to fry a 1 watt resistor. It is important that we ensure that any current limiting resistors can dissipate the power through them. The above situati ...

Test probe
A test probe (test lead, test prod, or scope probe) is a physical device used to connect electronic test equipment to a device under test (DUT). They range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
