Environmental condition, unknown effects over circuit and vague value of elements are main factors for paying to fuzzy variables in circuit analysis. This paper presents a new viewpoint in circuit solving with meanings of fuzzy current, voltage and so on or fuzzy values. From this standpoint, circuit is converted to a fuzzy differential equation with fuzzy variables (FDE-FV). Two conventional types of fuzzy derivatives are used in circuit analysis. This paper appropriates to explain uncertainty in current in resistance-inductor (RL) circuit for the first time. Existing uncertainty in memory cell is studied using fuzzy differential equation. Result of RL circuit analysis with fuzzy current shows that depend on type of excitation, suitable definition of fuzzy derivative must be used. Circuit behavior is justified using FDEs as well as in experimental works.
