The doorbell of a home requires 10 volts to operate. A transformer is used to connect a 120 v primary circuit within the home to the doorbell. The transformer in the doorbell has 500 turns on the primary coil and supplies the doorbell with 900 mA of current.
Required:
a. Determine whether the transformer features a step-up or step-down design.
b. Calculate the number of turns on the secondary coil.
c. Calculate the current that is drawn from the 120-V household circuit to operate the doorbell in mA.
