GATE Electrical Engineering (EE) 2015 Shift 1 Solved Paper

In the following chopper, the duty ratio of switch S is 0.4. If the inductor and capacitor are sufficiently large to ensure continuous inductor current and ripple free capacitor voltage, the charging current (in Ampere) of the $5\mathit{V}$ battery, under steady-state, is____. (the value of resistance is 3 ohms)
