Final answer:
Resistor color codes provide resistance values and tolerances. Red, Yellow, Green, Gold denotes a 2.4M ohm resistor with ±5% tolerance. Brown, Black, Orange, Silver equates to a 10k ohm resistor with ±10% tolerance, Blue, Violet, Red, Brown results in a 6.7k ohm resistor with ±1% tolerance, and Yellow, Purple (assumed Violet), Blue, Silver corresponds to a 47M ohm resistor with ±10% tolerance.
Step-by-step explanation:
The colors on a resistor are used to indicate its resistance value and tolerance. Here, we will determine the values for the given color-coded resistors:
- Red, Yellow, Green, Gold: The first two bands (Red and Yellow) give us the numbers 2 and 4. The third band (Green) represents the multiplier, which is 10^5. The Gold band represents a tolerance of ±5%. So, the resistance is 2,400,000 ohms (2.4M ohms) with a tolerance of ±5%.
- Brown, Black, Orange, Silver: The first two bands (Brown and Black) give us the numbers 1 and 0. The third band (Orange) represents the multiplier, which is 10^3. The Silver band represents a tolerance of ±10%. So the resistance is 10,000 ohms (10k ohms) with a tolerance of ±10%.
- Blue, Violet, Red, Brown: The first two bands (Blue and Violet) give us the numbers 6 and 7. The third band (Red) is the multiplier, which is 10^2. The Brown band represents a tolerance of ±1%. So the resistance is 6,700 ohms with a tolerance of ±1%.
- Yellow, Purple, Blue, Silver: Note that the color Purple is not standard in resistor color coding, and should likely be Violet. Assuming so, the first two bands (Yellow and Violet) give us the numbers 4 and 7. The third band (Blue) represents the multiplier, which is 10^6. The Silver band represents a tolerance of ±10%. So the resistance is 47,000,000 ohms (47M ohms) with a tolerance of ±10%.
