Work Example 19
NATEF Automotive Tasks:
A given V8 will have an ideal current draw of 200 amps.
The specs allow for a tolerance of plus or minus 10%. Starter
circuit resistance is 0.03 and battery voltage is 12.6 V.
Will the circuit fall within specifications?
Ohm's Law: Volts = Amps × Ohms
A car has 12.6 volts, and the resistance is 0.03 ohm.
Amps = 12.6/0.03 = 420 amps
Since 220 amps is the maximum range, the starter circuit is
not within range.
