A circuit of resistance R ohms and inductance L henries has a direct voltage of 230 V applied to it. 0.3 second after switching on, the current in circuit was found to be 5A. After the current has reached its final steady value, the circuit was suddenly sort-circuited. The current was again found to be 5A at 0.3 seconds after short-circuiting the coil. Find the value of R and L.
