//Multiple Choice

What is the total resistance of resistors in series? {
    =The sum of the individual resistances
    ~The product of the individual resistances
    ~The reciprocal of the sum of individual resistances
    ~None of the above
}

In a series circuit, the current through each resistor is\: {
    ~Different
    =The same
    ~Zero
    ~Dependent on voltage
}

If three resistors R1, R2, R3 are connected in series, the equivalent resistance Req is given by\: {
    =R1 + R2 + R3
    ~R1 + R2⋅R3
    ~R1 - R2 - R3
    ~R1⋅R2⋅R3
    ~None of the above
}

Which of the following is a characteristic of a series circuit? {
    ~The voltage is the same across all resistors.
    ~The current divides across all resistors.
    =The total resistance is greater than the largest individual resistance.
    ~The equivalent resistance is always smaller than the smallest resistor.
}

//True or False

The equivalent resistance of resistors in series is always less than the smallest resistor. {F}

In a series circuit, the current through each resistor is the same. {T}

The voltage across resistors in a series circuit is equal to the total voltage of the source. {T}
