What is the maximum resistance which can be made using five resistors each of $1/5 \ \Omega$ (in $\Omega$)?

If $R_{1}$ and $R_{2}$ are the resistances of filaments of a $400 \ W$ and a $200 \ W$ lamp,designed to operate on the same voltage,then

If a current of $0.5\;A$ is passed through an electric bulb for $1\;hour$, how much electric charge will pass through the bulb (in $C$)?

The electric potential of a positively charged body is positive,and the electric potential of a negatively charged body is negative.

$A$ torch bulb is rated $5\,V$ and $500\,mA$. Calculate its $(i)$ power,$(ii)$ resistance,and $(iii)$ energy consumed when it is lighted for $4$ hours.

If you connect three resistors having values $2 \, \Omega$, $3 \, \Omega$, and $5 \, \Omega$ in parallel, will the value of total resistance be less than $2 \, \Omega$, greater than $5 \, \Omega$, or lie between $2 \, \Omega$ and $5 \, \Omega$? Explain.
