Question

John connected 3 resistors in series. The equivalent resistance or series resistors is

the sum of the values of the individual resistors. If John used resistors which were
2.2 x 10² ohms, 3.3 x 10³ ohms, and 4.7 x 10 ohms; what was the equivalent
resistance in ohms? Show result in scientific notation.

Answer 1

`3.567 * 10^3`

Explanation:

`2.2 * 10^2 +3.3 * 10^3+4.7 * 10 \\ \\ =22 * 10+330 * 10 +4.7 * 10 \\ \\ =356.7* 10 \\ \\ =3.567 * 10^3`
