A dc network has an open circuit voltage of 5 V. When its terminals are short circuited a current of 5 A flows through the short circuit. If the short circuit is removed and a resistance of 1.5 Ω is

Assertion (A): A branch with no current through it can be replaced by an open circuit or short circuit.Reason (R): Reciprocity theorem is applicable only if the circuit has one source

In a DC arc welding operation, the voltage-arc length characteristic was obtained as Varc = 20+5l where the arc length l was varied between 5 mm and 7 mm. Here Varc denotes the arc voltage in Volts. T
