Two bulbs $X$ and $Y$ having same voltage rating and of power $40\, watt$ and $60\, watt$ respectively are connected in series across a potential difference of $300\, volt$, then
$X$ will glow brighter
Resistance of $Y$ is greater than $X$
Heat produced in $Y$ will be greater than $X$
Voltage drop in $X$ will be greater than $Y$
A ($100\, W$, $200\, V$) bulb is connected to a $160\, V$ power supply. The power consumption would be ............. $W$
Time taken by a $836\; W$ heater to heat $1\; litre$ of water from $10^{\circ} C$ to $40^{\circ} C$ is
How many calories of heat will be produced approximately in a $210\, watt$ electric bulb in $5$ minutes .............. $cal $
$A$ constant voltage is applied between the two ends of a uniform metallic wire. Some heat is developed in it. The heat developed is doubled if
The temperature at which thermal electric power of a thermo couple becomes zero is called
