A neon sign transformer has a 420W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil.
Part A
How many turns of wire does the secondary coil have? ( it is not 48750, 45500n 49636, or 5.0x10^4)
Part B
How many turns of wire does the secondary coil have?
Part C
The current in the primary coil?
Homework Answers
Part A: How many turns of wire does the secondary coil
have?
13000 volt sec/120 volts pri x500 turns primary = 5.42 x 10^4
turns
When the transformer is running at full power, what is the current
in the secondary coil?
amps sec = power /volt(sec)
= 420W /13kv
=32.3x 10^-3 amps
The current in the primary coil?
amps pri = power/ volts pri
= 420W /120v
=3.5 amps
