Technician A says that in a circuit that has 3 Ohms of resistance and operates on 12 volts, the amperage must be 4 amps. Technician B says that in a circuit has 3 Ohms of resistance and operates on 24 volts, the amperage must be 12 amps. Who is correct?

The technician that gave the correct statement is Technician A  

Determination of the current in the circuit for technician A

From the question given above, the following data were obtained:

  • Resistance (R) = 3 Ohms
  • Voltage (V) = 12 V
  • Current (I) =?

V = IR

12 = I × 3

Divide both side by 3

I = 12 / 3

I = 4 A

Thus, technician A is correct.

Determination of the current in the circuit for technician B

From the question given above, the following data were obtained:

  • Resistance (R) = 3 Ohms
  • Voltage (V) = 24 V
  • Current (I) =?

V = IR

24 = I × 3

Divide both side by 3

I = 24 / 3

I = 8 A

Thus, technician B is wrong as the current in the circuit is 8 A and not 12 A.

From the calculations made above, we can conclude that technician A is correct.
