For a type-A chopper, 'VS' is the source voltage, 'α' is the duty cycle and 'RL' is the load resistance. The average output voltage and current for this chopper are, respectively ______.
1
\(\frac{{{V_S}}}{{\left( {1 - \alpha } \right)}},\frac{{{V_S}}}{{\left( {1 - \alpha } \right){R_L}}}\)
2
\(\frac{{{V_S}}}{\alpha },\frac{{{V_S}}}{{\alpha {R_L}}}\)
3
\(\alpha {V_S},\frac{{\alpha {V_S}}}{{{R_L}}}\)
4
\(\left( {1 - \alpha } \right){V_S},\frac{{\left( {1 - \alpha } \right){V_S}}}{{{R_L}}}\)
