Owing to increase in number of the charges postponed on a chain the current frequency increases. In turn, growth of number of the charges postponed in unit of time is equivalent to increase in current in a chain and to reduction of its resistance, and it is possible to achieve it by means of a chain with the condenser.

Instruction
1. Collect a chain with the condenser in which sinusoidal tension creates the generator of alternating current.
2. At a zero tension at the time of short circuit of a key in the first quarter of the period tension on clips of the generator will begin to increase, and the condenser will begin to be charged. In a collected chain there will be current, but in spite of the fact that tension on generator plates still is not enough, the value of current in a chain will be the greatest (value of its charge).
3. Note that in process of reduction of the category of the condenser the current indicator in a chain decreases, and at the time of a full discharge the current is equal to zero. At the same time the value of tension on plates of the condenser will constantly grow, and at the time of a full discharge of the condenser will reach the maximum size (i.e. the value will be completely opposite to tension on generator plates). Thus, it is possible to draw a conclusion: in initial timepoint the current with the largest force will direct in not charged condenser, and in process of its loading will begin to decrease completely.
