Two electric bulbs $A$ and $B$ are rated as $60\, W$ and $100\, W$. They are connected in parallel to the same source. Then,
Both draw the same current
$A$ draws more current than $B$
$B$ draws more current than $A$
Current drawn are in the ratio of their resistances
If power in $3\,\Omega $ is $27\,W$ then what is the power in $2\,\Omega $ ................. $W$
What will happen when a $40\, watt$, $220\, volt$ lamp and $100\, watt$, $220\, volt$ lamp are connected in series across $40\, volt$ supply
Two bulbs are working in parallel order. Bulb $A$ is brighter than bulb $B$. If ${R_A}$ and ${R_B}$ are their resistance respectively then
An electric kettle takes $4\, A$ current at $220\,V.$ How much time will it take to boil $1\,\, kg$ of water circuits are consequences of from temperature $20\,^o C\, ?$ The temperature of $(a)$ conservation of energy and electric charge boiling water is $100\,^o C.$ ............... $min$
Which device is used to transmit voltage over large distance ? why ?
