Heating Element
A manufacturing engineer is reviewing the schematics for a certain heating element. If the drawing allows a 0.5 amp current when 60 volts are applied, what is the heating element’s resistance?
Hint
Ohm’s law:
$$$V=IR$$$
where
$$V$$
is the voltage,
$$I$$
is the current, and
$$R$$
is the resistance.
Hint 2
Solve for resistance:
$$$R=\frac{V}{I}$$$
Ohm’s law:
$$$V=IR$$$
where
$$V$$
is the voltage,
$$I$$
is the current, and
$$R$$
is the resistance. Rearranging the equation to solve for resistance:
$$$R=\frac{V}{I}=\frac{60V}{0.5A}=120\:\Omega$$$
$$$120\:\Omega$$$
