Question

Open-circuit voltage of 60 v and current of 160a were the welding conditions for arc welding of a certain class of steel strip of thickness 10 mm. For arc welding of 5mm thick strip of the same steel, the welding voltage and current would be (a) 60 v and 80 a (b) 120 v and 160 a (c) 60 v and 40 a (d) 120 v and 40 a

Answer 1

Answer:

The answer will be No A:60v and 40 A.

As Volt is the potential difference while Ampere is the amount of Current.
