  1. The total current in a parallel circuit is equal to the:
    1. current in any one of the parallel branches
    2. sum of the currents through all the parallel branches
    3. applied voltage divided by the value of one of the resistive elements
    4. source voltage divided by the sum of the resistive elements

  2. If a 2.2 megohm and a 100 kilohm resistor are connected in series, the total resistance is:
    1. 2.1 megohm
    2. 2.11 megohm
    3. 2.21 megohm
    4. 2.3 megohm

  3. Two resistors are in parallel. Resistor A carries twice the current of resistor B which means that:
    1. A has half the resistance of B
    2. B has half the resistance of A
    3. the voltage across A is twice that across B
    4. the voltage across B is twice that across B

  4. A current of 500 milliamp passes through a 1000 ohm resistance. The power dissipated is:

    2. 2.5 watt
    3. 25 watt
    4. 250 watt

    1. 0.01 watt
    2. 0.1 watt
    3. 1 watt
    4. 10 watt

  6. One GHz is equal to:
    1. 1000 kHz
    2. 10 MHz
    3. 100 MHz
    4. 1000 MHz

  7. The material separating the plates of a capacitor is the:
