Final answer:
A
,
incandescent bulb draws
of current calculated using the formula
where I is the current,
is the power
(
), and
is the voltage (
).
Step-by-step explanation:
To find out how many Amps a
incandescent bulb draws, we can use the relationship between power, voltage, and current, which is given by Ohm's law. The formula to calculate current
.
when power
and voltage
are known is
.
Applying this formula we have a power of
and a voltage of
, which gives us:
.
Therefore, a
incandescent bulb draws
. It's important to remember that this is the average current, as household power is AC (alternating current) and varies over time.
