An electric doorbell requires a 12 V, 60 Hz ac supply. If the transformer is connected the wrong way around the circuit, what voltage is supplied to the doorbell?
If figured the voltage ratio would now be 120/12, or 10, and 10 x 120 = 1200V. Is this right?
My other idea was that connecting the transformer the wrong way would simply supply the doorbell with 120 V.
Which is right?
Thanks
