Q2. How to calculate for the resistance
Ans. 
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

Q3. What is colour coding
Ans. 
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

Q4. Colours coding for the resistance
Ans. 
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%.
