The current in the circuit shown in the figure. What will be the current in the circuit?

Correct answer: B. 1/10A

  • A. 1/45A
  • B. 1/10A
  • C. 1/5A
  • D. 5A

Explanation

Given,Voltage = 2Vr1 = 30Ωr2 = 30Ωr3 = 30ΩTo find,The current in the circuitSolution,The current in the circuit shown in the figure is 0.1 A.We can simply find the current in the circuit by using the formula ofV = IRr1 and r2 are connected in series so the resistance would be r4 = r1+r2r4 (in series) =30+30 = 60Ωr3 and r4 are connected in parallel so resistance would be1/r5 = 1/r3+1/r4 = 1/60+1/30 = 3/60 = 1/20 r5 = 20Ω I = V/R = 2/20 = 1/10 = 0.1 AHence, The current in the circuit shown in the figure is 0.1 A.

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
