Rotating devices have moving parts while static devices do not.

• Rotating devices have components that move in a circular motion, such as motors or turbines.

• Static devices have stationary components, like resistors or capacitors.

• Rotating devices typically require maintenance for lubrication and alignment.

• Static devices are generally more reliable and have longer lifespans.

• Examples of rotating devices include electric mot...read more

Resistance can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current.

• Use Ohm's Law: R = V / I

• Resistance is measured in ohms (Ω)

• Voltage is measured in volts (V)

• Current is measured in amperes (A)

• Example: If the voltage is 12V and the current is 2A, the resistance would be 6Ω

Colour coding is a system of assigning colours to objects or information to convey meaning or identification.

• Used in various fields such as electronics, wiring, and safety equipment

• Example: Red wire indicates positive polarity in electronics

• Example: Red colour on safety equipment indicates fire hazard

• Helps in quick identification and reduces errors

Color coding is used to identify the resistance value of a resistor.

• The first band represents the first digit of the resistance value.

• The second band represents the second digit of the resistance value.

• The third band represents the multiplier.

• The fourth band represents the tolerance.

• For example, a resistor with brown, black, red, and gold bands has a resistance value of 1.0 ohm with a tolerance of +/- 5%.

Embedded system is a computer system designed to perform specific tasks, with dedicated functions and limited resources.

• Embedded systems are found in various devices such as smartphones, cars, medical equipment, and home appliances.
