BALLISTIC GALVANOMETERS

BALLISTIC GALVANOMETERS:

Specifications:

• Used for measurement of small quantities of electrical charge and currents.
• Leveling Screws for balancing the coil.
• Coil with mirror suspended between long suspension at the upper end and a spring at lower end.
• Suspension and spring are made of special alloy to provide high degree of sensitivity to the movement.
• Movement housed in a Bakelite case, rigid and robust.
• Clamping arrangement for transportation.
• Consistent sensitivity over a longer period.
• Strip provided for damping its ballistic movement.
• Coil Resistance (Ohm) : 100.
• Charge Sensitivity (mm/µC) : 300 .
• Current Sensitivity (mm/µA) : 1000.
• Time Period (seconds) : 12.
• Critical Damping Resistance (Ohm) : 2000
