Question 407505: The heating element is rated 1.80 kW when operating voltage is 0.24 kV.
a)What is the current through it?
b)What would its power consumption be if the potential difference drops to 0.12 kV?
You can put this solution on YOUR website! The heating element is rated 1.80 kW when operating voltage is 0.24 kV.
a)What is the current through it?
------------------
P = I*V
1800 = I*240
I = 1800/240 = 7.5 amps
-----------------
b)What would its power consumption be if the potential difference drops to 0.12 kV?
E = I*R
R = E/I = 240/7.5 = 32 ohms
------------
P = E^2/R
@ 120 volts
P = 120^2/32 = 450 watts
