Question

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

Answer 1

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

Answer 2

since 1MOhm= 10^6 Ohms

Answer 3

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

Answer 4

is that correct? :)

Answer 5

that's right!

Answer 6

yay! thanks!
