Question

How much resistance is ther in a 12-volt circuit with a 2-amp current

Answer 1

GIVEN -> Voltage in circuit = 12 V 
 Current in circuit = 2 A  
To find resistance we will use the well known equation or Ohms Law equation,
 which is; V = IR 
 hence R = V/I
  R = (12 V) / 2 A
  R = 6 ohm 
 therefore, ideally the resistance in the circuit would be equal to 6 ohms.
