    ~Volt
    ~Ohm
    =Ampere
    ~Coulomb
}

Electric current is the flow of\: {
    ~Protons
    =Electrons
    ~Neutrons
    ~Atoms
}

One ampere of current is equal to the flow of\: {
    =1 coulomb per second
    ~1 joule per second
    ~1 watt per second
    ~1 ohm per second
}

What is the instrument used to measure electric current? {
    ~Voltmeter
    =Ammeter
    ~Galvanometer
    ~Multimeter
}

In which direction does conventional current flow? {
    =From positive to negative terminal
    ~From negative to positive terminal
    ~In both directions
    ~There is no specific direction
}

//True or False

Electric current is a scalar quantity. {F}

A current of 2 amperes means 2 coulombs of charge are flowing per second. {T}

The direction of electron flow is the same as the direction of conventional current. {F}

The unit of current is measured in joules. {F}

An ammeter must be connected in series to measure the current correctly. {T}

//Fill in the blanks



//Numericals



//Match the following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Electric current -> Flow of charge
=Ammeter -> Measures current
=Ampere -> SI unit of current
=Conventional current -> Flows from positive to negative terminal
=One ampere -> 1 coulomb per second
}
