Dynamic properties of electrical circuits containing a Josephson junction are studied analytically by approximating the sinusoidal current-phase relation by a triangular one. Analytical expressions are obtained for the circuit-parameter dependences of transient voltage waveforms, ac ripples of stationary-state voltage oscillation and minimum currents in several typical circuits, which are shown to be in good agreement with numerical results. It is also shown that these quantities can be well characterized in simple forms in terms of a frequency peculiar to each circuit.
