To find the resistance of the element when connected to a $210V$ dc source.

Solution:

The power of the heating element is $630$ Watt and its voltage is $210V$. Thus, the current drawn can be calculated with the formula

$P=VI$,

where $P$ denotes the power, $V$ stands for the voltage and $I$ is the symbol of the current.

So the value of the current drawn $=VP =210630 =3A$

And the resistance of the element when connected to a $210V$ dc source = $IV =3210 =70Ω$
