No current flows between two charged bodies when connected,if they have the same

If the current $I$ through a resistor is increased by $100\%$ (assume that temperature remains unchanged), the increase in power dissipated will be ........ $\%$

Resistance of a metal wire of length $1\, m$ is $26\, \Omega$ at $20^{\circ} C$. If the diameter of the wire is $0.3\, mm$,what will be the resistivity of the metal at that temperature?

What is the $SI$ unit of electric charge?

If $4.8 \text{ A}$ current is passed through an electrical appliance,then the number of electrons passing through it in $1 \text{ second}$ will be $......$

Five bulbs are connected in a parallel circuit. If the second bulb blows out,what happens?
