RESISTANCE INCREASES

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.

TECH A SAYS AN OPEN CIRCUIT CAUSES UNWANTED VOLTAGE DROPS.  TECH B SAYS HIGH RESISTANCE PROBLEMS CAUSED INCREASED CURRENT FLOW.

WHAT IS THE CURRENT IN A 12 VOLT CIRCUIT WITH TWO 3 OHM RESISTORS CONNECTED IN PARALLEL?

GASSING IN BATTERY

FULLY CHARGE BATTERY VOLTAGE

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.
