Electronics-Series Circuits Question and Answer
2. If the resistance total in a series circuit doubles, current will:
- be the same
- be doubled
- reduce source voltage
- be halved
3. Power is defined as:
- the rate at which work is done
- work
- the conversion of energy
- joules
4. Kirchhoff’s voltage law states that:

- the algebraic sum of the resistances is equal to the sum of the voltages
- the algebraic sum of the individual currents around a closed loop is zero
- the voltages developed across each element in a series circuit are identical
5. If series current doubles, then:
- resistance is halved
- voltage is doubled
- voltage is reduced
- resistance is doubled

8. A string of resistors in a series circuit will:
- divide the source voltage in proportion to their values
- reduce the power to zero

9. Given a series circuit containing resistors of different values, which statement is not true?
- The current through each resistor is the same.
- The sum of the voltage drops across each resistive element will be equal.
- The total resistance is the sum of the value of the resistors.
- The voltage drop across each resistor is the same.
