Calculate the Current across the 20 Ohm Resistor

Answer: B. 10 A

The current across the 20-ohm resistor in the circuit shown above is 10 A.

Solution:

All the given resistors are connected in parallel across the 200 V source.

The current through the 20-ohm resistor = V/R=200/20=10 A

Hence option B is the correct answer.
