Direct Current Circuits Part 2

In the last programme we introduced the ideas of current, voltage and resistance on which the theory of direct current and voltage circuits depends. We found that simple circuits could be modelled using idealised current and voltage generators and saw how these idealisations needed to be modified in practice. Two important circuit configurations, the potential divider and the current splitter, were introduced. In this programme we shall extend these ideas to more complicated circuits and develop methods of analysis and design which will enable us to deal with them.
