Answer :
Explanation:
It is known that relation between voltage and power is as follows.
Power (P) = Voltage (V) × Current (I)
or, I = [tex]\frac{P}{V}[/tex]
Since, it is given that the elements are in parallel so the currents will get added. Therefore, total current in the line will be as follows.
I = [tex]\frac{P_{1}}{V} + \frac{P_{2}}{V} + \frac{P_{3}}{V} + \frac{P_{4}}{V} + \frac{P_{5}}{V}[/tex]
= [tex]\frac{1}{120} (100 + 180 + 230 + 1050 + 240)[/tex]
= [tex]\frac{1800}{120}[/tex]
= 15 A
Therefore, we can conclude that 15 ampere current is flowing in the line.
