• Subtopic: Calculating Current for Different Resistances To find the current $I$ for different resistances, we use the formula $I = \frac{V}{R}$, where $V = 10 \, \text{V}$. a) For $R = 50 \, \text{Megaohm}$: $$I = \frac{10}{50 \times 10^6} = \frac{1}{5} \times 10^{-6} \, \text{A} = \frac{1,000}{5} \times 10^{-3} \, \text{mA}$$ b) For $R = 50 \, \text{Kiloohm}$: $$I = \frac{10}{50 \times 10^3} = \frac{1}{5} \times 10^{-3} \, \text{A} = \frac{1}{5} \, \text{mA}$$ c) For $R = 25 \, \text{Kiloohm}$: $$I = \frac{10}{25 \times 10^3} = \frac{10}{25} \times 10^{-3} \, \text{A} = \frac{2}{5} \, \text{mA}$$
