    OHMS LAW
  2. TYPE OF DIAGRAM/CHART USED TO SHOW HOW CIRCUITS ARE CONSTRUCTED
    SCHEMATIC
  3. AMMETER WITHOUT AN INDUCTIVE LEAD IS ALWAYS PLACED IN _____ WITH THE CIRCUIT
    SERIES
  4. VOLTMETER IS ALWAYS PLACED IN _____ WITH THE CIRCUIT
    PARALLEL
  5. RESISTANCE INCREASES
    CURRENT DECREASES
  6. TECH A SAYS THAT MAGNETISM IS A SOURCE OF ELECTRICAL ENERGY IN AN AUTOMOBILE. TECH B SAYS CHEMICAL REACTION IS A SOURCE OF ELECTRICAL ENERGY IN AN AUTOMOBILE.
    BOTH TRUE
  7. TECH A SAYS AN OPEN CIRCUIT CAUSES UNWANTED VOLTAGE DROPS.  TECH B SAYS HIGH RESISTANCE PROBLEMS CAUSED INCREASED CURRENT FLOW.
    NEITHER
  8. WHAT IS THE CURRENT IN A 12 VOLT CIRCUIT WITH TWO 3 OHM RESISTORS CONNECTED IN PARALLEL?
    8 AMPS

    A=12V/3OHMS=4+4= 8AMPS
  9. GASSING IN BATTERY
    SULFATION DUE TO RAPID CHARGING

    OVERCHARGING
  10. FULLY CHARGE BATTERY VOLTAGE
    12.6 VOLTS
  11. TECH A USES VOLTMETER TO CHECK THE OPEN CIRCUIT VOLTAGE OF A BATTERY.  TECH B USES THE RESULTS OF AN OPEN CIRCUIT VOLTAGE TEST TO DETERMINE A BATTERIES STATE OF CHARGE.
    BOTH TRUE
  12. PART OF THE STARTER MOTOR CIRCUIT
    BATTERY, STARTER MOTOR, ENGINE BLOCK 

    STARTING SYSTEM SAFETY SWITCH?
  13. HARD STARTING CONDITION
    LOSE BATTERY CABLE CONNECTIONS
  14. A CIRCUIT HAS A SHORT TO GROUND.
    LOW RESISTANCE PATH TO GROUND.
  15. TYPE OF RESISTORS USED IN AUTOMOBILE CIRCUITS
    FIXED VALUE, TAPPED OR STEPPED, VARIABLE
  16. METER USED TO TEST CIRCUIT CONTINUITY AND RESISTANCE, WITH NO POWER APPLIED
    OHMMETER
  17. AUTOMOTIVE CIRCUITS FOUR BASIC PARTS: POWER SOURCE, CONDUCTORS, LOADS, AND _____
    CONTROLLERS (SWITCHES/RELAYS)
  18. MINIMUM VOLTAGE REQUIRED FOR THE STARTER TO CRANK THE ENGINE
    9.6 VOLTS
  19. BATTERY VOLTAGE LEAKAGE TEST CONDUCTED
    VOLTMETER BLACK LEAD TO NEGATIVE TERMINAL, RED LEAD TO POSITIVE TERMINAL ACROSS THE CASE TOP AND SIDES
  20. TECH A SAYS THAT A 12 VOLT LIGHT BULB THAT DRAWS 12 AMPS HAS A POWER USAGE OF 1 WATT.  TECH B SAYS THAT A MOTOR THAT HAS 1 OHM OF RESISTANCE HAS A POWER RATING OF 144 WATTS IF ITS CONNECTED TO A 12 VOLT BATTERY.
    B ONLY

    • A. P=IxE P=12x12=144 WATTS
    • B. A=V/R A=12/1=12AMPS
