    10 A
  • b)
    15 A
  • c)
    19 A
  • d)
    23 A
Correct answer is option 'C'. Can you explain this answer?

Potential of 20V20V will be same across each resistance current




∴ Total current drawn from circuit
I = I1 + I2 + I3
= 10 + 5 + 4 = 19A

Potential of20V20Vwill be same across each resistance current∴ Total current drawn from circuitI = I1 + I2 + I3= 10 + 5 + 4 = 19A
