## anonymous one year ago When 2.0 A of current moves across a 1.0 MΩ resistor, then what is the drop in voltage (∆V) across the resistor? A. 2.0 × 10^0 V B. 2.0 × 10^2 V C. 2.0 × 10^3 V D. 2.0 × 10^6 V

here we have to apply the Ohm's law: $\Delta V = RI = 2 \times 1 \times {10^6}$

2. Michele_Laino

since 1MOhm= 10^6 Ohms

3. anonymous

ohh ok! so we get choice D as our solution?

4. anonymous

is that correct? :)

5. Michele_Laino

that's right!

6. anonymous

yay! thanks!
