Answer 1

1] False . The SI unit of charge is coulomb and the SI unit of P.D is Volt.
2] True.
3] True.
4] True
5] False. The resistivity of pure metals is less than that of alloys.
6] False. The electric bulb consists of the filament whose melting point is                       high.

Answer 2

false The SI unit of charge is coulomb 

false it is connected parallel

true

true

false resistivity of alloy is more than metals

false melting point should be high
