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

Answer:

$3.567 \times 10^3$

Step-by-step explanation:

$2.2 \times 10^2 +3.3 \times 10^3+4.7 \times 10 \\ \\ =22 \times 10+330 \times 10 +4.7 \times 10 \\ \\ =356.7\times 10 \\ \\ =3.567 \times 10^3$
