Ohm’s Law Tolerance of a Resistor Tolerance = value of resistor x value of tolerance band  Gold = ± 5% Silver = ± 10 % None = ± 20% Types of Resistor And then And then Surface Mount Device The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the […]

Some Important points on FREQUENCY

Pitch vs Frequency A high pitch sound = A high frequency sound wave A low pitch sound = A low frequency sound wave. Wave length vs Frequency As a wavelength increases in size =  its frequency and energy (E) decrease Frequency vs Circuit Current Bandwidth Bandwidth is defined as the difference between the highest and […]
