คุณลักษณะ

• Use of 6th Grade Electricity
• This device is an integral part of a large-capacity condenser used for electricity storage experiments using a general contractor V3 (hand-cranked generator) and a large meter that can be seen at a glance.
• The meter gives a visual indication of how much electricity is being stored and how much electricity is being consumed, making it easier to adjust standards when experimenting with different amounts of storage.
