Solve the following automotive-services problems based on the examples shown previously. Voltage = 12 v Current = 48 amps Resist
yawa3891 [41]
For this case the first thing you should know is that we have the following definition:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 Therefore, by clearing the Resistance we have:
 R = V / I
 Substituting the values:
 R = 12/48
 R = 1/4 ohms
 Answer:
 The value of the resistance is: 
 R = 1/4 ohms
