3 Heat switch.
I test a 3 heat switch and find that in the low position and medium position one of the terminals is common. What would I connect this terminal too and why?...
Simmerstat.
What is the function of the heating element in a simmerstat?....And If I use my ammeter to test across it, what reading am I likely to get ohms or Kilo-ohms?..
Motors.
I've wired up a motor and connected it to a conveyor that needs to go from left to right. But instead it goes the opposite direction. Why is this and how would I change the wiring to have the motor turn the opposite direction?.
Appliance testing.
I've tested a class one appliance, And have found that when I connect my meter between earth and the metal case I get 5 ohms. Is this safe to use?...If so why?..And if not why?...
Protection.
I have a bench grinder with a powerful ac motor in it. I have blown the fuse when using it.
From the label printed on it I have calculated that it draws 5.5 amps. But when I use a 6 amp fuse it keeps blowing. Why would this happen when the fuse is rated higher than the current drawn by the appliance?.
