Class 10 Electricity Test1

SI unit of Electric current is

• volt

• ampere

• joule

• coulomb

The physical quantity responsible for the current flow is

• Electric potential

• Electricity

• Electric potential difference

• Resistance

SI unit of electric charge is

• ampere

• volt

• coulomb

• joule

Magnitude of charge on an electron is (a)   x 10^-19 C.

Define Electric potential difference.

If 300C of charge flows through the cross section of a wire in one minute, the current flowing through the wire is

• 30A

• 10A

• 300 A

• 5A

If 5 electrons are gained by an object, the charge on that object will be

• - 16 x 10^-19 C

• 16 x 10^-19 C

• -8 x 10^-19 C

• -80 x 10^-18C

As per Ohm's law, if physical conditions remain same, the electric current flowing through a conductor is (a)   to the electric potential difference across the two ends of the conductor.
