Answer:
Resistance = 4465 Ω - 4935 Ω
Explanation:
The color bands in a four band resistors are read as follows:
Band 1: 1st digit of Resistance
Band 2: 2nd digit of Resistance
Band 3: Multiplier Value
Band 4: Tolerance
Now interpreting our code:
Band 1 (Yellow) = 4
Band 2 (Violet) = 7
Band 3 (Red) = 10²
Band 4 (Gold) = ±5%
Therefore,
Resistance = 47 x 10² Ω ± 5%
Resistance = 4700 Ω ± 5%
So, the range can be calculated as:
Lower Limit = 4700 Ω - (0.05)(4700 Ω)
Lower Limit = 4700 Ω - 235 Ω
Lower Limit = 4465 Ω
No, for upper limit:
Upper Limit = 4700 Ω + (0.05)(4700 Ω)
Upper Limit = 4700 Ω + 235 Ω
Upper Limit = 4935 Ω
Thus, the acceptable range of resistance will be:
Resistance = 4465 Ω - 4935 Ω
