Electrical
Vibrator
A Steel Wire With A Hook On One Side Is Made To Pass
Through Solenoid And A Horse Shoe Magnet. When 220 Volts
A.C. Current Is Passed Through The Solenoid The Steel
Wire Reverse With Every Charge Of A.C Current Direction
And Vibrates With The Frequency Of A.C. Mains. The Frequency
Is Calculated As Is Done In Melde's Apparatus. It Can
Also Be Used To Measure The Capacity Of A Condenser
By Applying The Formula C=1/Vf , Where C Is The Capacity
Of The Condenser ,The Microameter Current . V The Main
Voltage And F The Frequency.
