How to calculate the resistance of a circuit?
1. Say you have a nominal 22Ω resistor with 5% tolerance. 2. The actual resistor value could be as low as 22Ω – 5% of 22Ω 3. Or the actual resistor value could be as high as 22Ω + 5% of 22Ω 4. Do the calculation to find that 5% of 22Ω is 1.1Ω 5. The actual resistor value could be as low as 22Ω – 1.1Ω = 20.9Ω
How to calculate the maximum resistance of gold?
Gold has a tolerance of 5%. So 22x (5/100) = 1.1. Max Resistance = 22+1.1 and Min Resistance = 22-1.1 2) 6.8 kilo ohms = blue grey red gold. Gold has a tolerance of 5%. So 6.8k x (5/100) = 340. Max Resistance = 6.8k + 340. and so on…
What happens if the chassis is only grounded at one point?
But if the chassis is only grounded at one point, current cannot flow through the chassis, and the relationship between magnetic flux and electricity cannot be exercised. Ground loops, which cause induced EMF (noise), are especially problematic for noise-sensitive applications such as instrumentation and audio.
How are grounds and Commons connected to each other?
There are many rules as to how to connect circuit commons to each other, to the chassis ground (if there is one) and to the Earth ground (again, if there is one). Each of these rules has many legitimate exceptions which means the final decision is determined by regulatory requirements, good engineering practice, and performance goals.
