Why is a Tesla coil so loud?

Why is a Tesla coil so loud?

A Tesla Coil produces sound by switching on and off a certain number of times per second, causing air molecules around it to heat up and vibrate. Music can be played with a Tesla Coil by changing the frequency: more sound waves per second produce a higher pitch, while fewer sound waves per second produce a lower pitch.

How many amps does a Tesla coil need?

Input power to the coil is raw unrectified AC at 3000 volts rms with a current of 0.5 amps. Peak voltage is over 4000 volts and is supplied by a conventional MOT transformer transformer being fed by a voltage adjustable variac for power output control.

How do you measure the voltage of a Tesla coil?

Re: measure the secondary voltage of a tesla coil. The primary induces additional voltage in the secondary: V = 2*pi*f*M*Ipri, where M is the mutual inductance. When adding this voltage to the voltage caused by Ibase, one has to observe the phase relationship between the voltages.

How do you calculate the voltage of a Tesla coil?

  1. Formulas for Tesla Coils. v. 3.0.
  2. Ohm’s Laws. V = I x R = P / I = SQRT(P x R)
  3. Resonate Frequency. Fo = 1 / (2 x pi x SQRT(L x C))
  4. Reactance. Xl = 2 x pi x F x L.
  5. RMS. Vpeak = Vrms x SQRT(2) For sine waves only.
  6. Energy. E = 1/2 x C x V^2 = 1/2 x L x I^2.
  7. Power. P = E / t.
  8. Helical Coil. Lh = (N x R)^2 / (9 x R + 10 x H)

What happens if you turn off the Tesla coil?

The primary capacitor can hold a lethal charge for quite a while, even after turning off the Tesla coil. The power supply will need to output a dangerously high voltage (at least 5000 volts, otherwise the spark gaps may not operate properly). The spark gaps produce loud noise and UV radiation.

How do you increase the voltage on a Tesla coil?

Use a variac to increase NST supply voltage to 140V / 240V. Move the primary coil closer to the secondary coil (unless you see racing arcs on the secondary coil). Increase the size of the top load. How much will my electrical bill increase after running my Tesla coil?

How many amps can the primary capacitor of a Tesla coil?

The primary circuit can contain hundreds of amps, which is certainly more than enough to be lethal. The primary capacitor can hold a lethal charge for quite a while, even after turning off the Tesla coil.

How much does it cost to run a Tesla coil?

Electricity typically costs about $0.10 / kWh (kilowatt hour). Therefore to operate a typical Tesla coil for 1 hour will cost about $0.10 (however, it’s very rare that a Tesla coil will be operated continuously for an hour). If I switch from a 9kV NST to a 15kV NST will I have to rebuild the entire Tesla coil?
