In which test the power of supply unit is kept switched off and the resistance at the divergent point is measured in power supply unit in troubleshooting of power supply unit? Correct Answer Cold

In the cold test the power of supply unit is kept switched off and the resistance at the divergent point (common supply point) is measured. If the resistance is zero (short) the fault is either in the supply line of any of the stages being fed by power supply unit or in the supply unit itself.
