An iron resistance! We'll test it :-)
Attention, it is a 110 Volt model :-) Its resistance opposes 22 ohm
110 V / 22 Ohm = 5 A; 5 A * 110 V = 550 Watts (otherwise U² / R: 110² / 22 = 550 W)
500 to 1,000 Watt for an iron: the resistance is correct!
This device measures U voltage, I current, P power in Watt and energy in Wh
This resistance is already at 40 ° C., measured at the laser thermometer
4.2 Ampere at 28 V = 120 Watts as displayed
The temperature exceeded 190 ° C
In spite of the stop, by the inertia, the body of the resistance still rises (+ 250 ° C)
Note the 'pretty smoke on the side must also! Any resistance CHAUFFE :-)
I will power a fluorescent tube end resistor
This resistance facilitates the gaseous state of the mercury for the lighting of the fluorescent tubes
