Work Step by Step
Statement A is true. The current through resistors in series is the same.
Statement B is false. The current through resistors in series is the same.
Statement C is false. $P=I^2R$ and the current through resistors in series is the same, but $R_2 \gt R_1$.
Statement D is true. $P=I^2R$ and the current through resistors in series is the same, and $R_2 \gt R_1$.
Statement E is false. $V=IR$ and the current through resistors in series is the same, but $R_2 \gt R_1$.
Statements F and G are false, and H is true. Current flows from higher electric potential to lower electric potential.
