Two resistors of resistance $2 \,\Omega $ and $4\, \Omega $ when connected to a battery will have
same current flowing through them when connected in series
same current flowing through them when connected in parallel
same potential difference across them when connected in series
different potential difference across them when connected in parallel
Should the resistance of an ammeter be low or high? Give reason.
The flow of charge through a conducting wire connected to a cell is the result of chemical reaction inside the cell.
