|---|---|---|---|---|---|
| show | An electromagnetic device changing AC from low voltage to high votage, and vice versa, with loss of an appreciable amount of energy.
🗑
|
||||
| Which current does a transformer work with (AC or DC)? | show 🗑
|
||||
| show | The emf induced in secondary coil is to the emf in the primary coil, as the number of turns in the secondary coil is to the number of turns in the primary coil.

|
||||
| show | Variable resistor designed to regulate filament current.
🗑
|
||||
| show | Secondary voltage = Primary Voltage (x) # of Secondary Turns / # of Primary Turns
🗑
|
||||
| Define the formula for calculating secondary current using primary current, #primary turns and #secondary turns | show 🗑

|
||||
| Define step-down transformer. | show 🗑
|
||||
| show | When 2nd coil has more turns than 1st coil, and puts out a HIGHER voltage than supplied to it.
🗑
|
||||
| What is another name for transformer? | show 🗑
|
||||
| What is the difference between the primary coil and secondary coil? | show 🗑
|
||||
| show | 1st coil (primary)
🗑
