Signal generator‘s internal impedance is purely resistive and has an open-circuit voltage of 3.5 V. When the generator is loaded with 22 ohms of resistance, its terminal voltage drops to 2.8 V
A project manager placed an order for ball bearings for some heavy duty manufacturing machinery. What is the surface area in square millimeters of one of these bearnings if it has a diameter of 0.4
The springs effect is addressed below. As a relay some contacts are connected to, and move with, the armature. Other contacts are stationary and would make or break contacts as the armature moves.
Frequently, the output of transducers are much smaller than what an A/D converter expects on its input. That would require an amplifier to match it. Sometimes the output does not start at 0V. Usuall
