About This Product
A ballistic galvanometer is used to measure the total charge that passes through its coil in a short pulse, because the first swing of the coil depends on that charge. In school physics it is used for experiments such as charge on a capacitor and electromagnetic induction. Its long time period lets the coil swing slowly enough for the first throw to be read from the mirror scale.
Frequently Asked Questions
Q1. What is the time period of the moving coil?
The time period of the moving coil is 10 to 12 seconds.
Q2. How is the coil damped?
The coil can be damped by a lever when it is not in use, and a zero adjuster is provided at the top.
Q3. Can students see the parts inside?
The whole front panel is covered by a glass plate so the teacher can demonstrate each part of the galvanometer.
