Question

What is the largest current you would expect through a 15kΩ, 2.0% resistor when connected to a 5.0v supply? Give your answer in mA

Answer 1

$-2 \% \quad \text{is} \quad \text{15000 ∙ 0.98 = 14700 Ω } \\ I = \frac{U}{R}, \\ \quad I=\frac{5}{14700} \approx \text {0.00034=0.34 mA} \\ \text{Answer: } I_{max} = \text{0.34 mA}$
