For blonde hair, or to add subtle highlights, mix 1/2 cup of strong chamomile tea, Â¼ cup fresh lemon juice, and Â¼ cup coconut oil in a blender until emulsified. Apply to hair and roots and cover with a shower cap. Sit in the sun, or use a hair dryer to keep the cap warm for 45 minutes to 75 minutes.
Ballasts limit the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases.
The fluorescent tube converts electrical energy into light. much more efficiently at high frequencies than at line. frequencies of 50 or 60Hz. Typical ballast frequencies are in. the range 40kHz to 150 kHz. When regulating the current the excess voltage is. dropped across the leakage inductance of the ballast with. minimal Watts loss as compared to the copper losses of. conventional ballast. Electronic ballasts are commonplace, reliable and efficient.
