Two bulbs, one of $200 \,W$ and the other of $100 \,W$ are connected in series with a $100 \,V$ battery which has no internal resistance. Then,
the current passing through the $200 \,W$ bulb is more than that through the $100 \,W$ bulb
the power dissipation in the $200 \,W$ bulb is more than that in the $100 \,W$ bulb
the voltage drop across the $200 \,W$ bulb is more than that across the $100 \,W$ bulb
the power dissipation in the $100 \,W$ bulb is more than that in the $200 \,W$ bulb
If a wire of resistance $20\,\Omega $ is covered with ice and a voltage of $210\, V$ is applied across the wire, then the rate of melting of ice is .................. $g/s$
In the circuit shown in figure, the power which is dissipated as heat in the $6\,\Omega $ resistor is $6\,W$. What is the value of resistance $R$ in the circuit? ................ $\Omega$
An expression for rate of heat generated, if a current of $I$ ampere flows through a resistance of $R$ $\Omega$, is
When two identical batteries of internal resistance $1 \Omega$ each are connected in series across a resistor $\mathrm{R}$, the rate of heat produced in $R$ is $J_1$. When the same batteries are connected in parallel across $R$, the rate is $\mathrm{J}_2$. If $\mathrm{J}_1=2.25 \mathrm{~J}_2$ then the value of $\mathrm{R}$ in $\Omega$ is
In the circuit shown in figure, if ammeter and voltmeter are ideal, then the power consumed in $9 \,\Omega$ resistor will be .......... $W$
