Ohm’s law (which should be familiar) is a very useful rule. Note that it only applies to resistive loads however. The impedance of other passive components may vary with (e.g.) frequency (e.g. capacitors) and many components do not obey this rule at all (diodes, transistors etc.). Resistance determines how much charge flows per second when …
Basics of Electrical. Instrumentation engineer must be thorough with electrical fundamentals. What is … Charge? Charge is measured in coulombs and is the amount of “electricity” present (or flowing). Charge can be positive or negative. Like charges repel each other. Unlike charges attract each other. In the vicinity of a charge there is an electric …
Analog Signal Analog signals are continuous signals that vary in amplitude and frequency over time. They are represented as smooth, continuous waves that can take on an infinite number of values. Examples of analog signals include sound waves, light waves, and radio waves. Advantages of Analog Signal Natural representation: Analog signals are natural representations of …
