Resistors in Series and Parallel: a 3D model for Class 10 Science, covering In series the same current flows through every part (1 A here); the resistors do not use up current., In series the potential differences add up to the source voltage: V1 + V2 = 2 V + 4 V = 6 V., Equivalent resistance in series: Req = R1 + R2 = 2 + 4 = 6 ohm, so I = V / Req = 6 / 6 = 1 A., In parallel every branch has the full source voltage across it (6 V across R1 and across R2)., In parallel the branch currents add: I = I1 + I2 = 3 A + 1.5 A = 4.5 A..

Topics

  • In series the same current flows through every part (1 A here); the resistors do not use up current.
  • In series the potential differences add up to the source voltage: V1 + V2 = 2 V + 4 V = 6 V.
  • Equivalent resistance in series: Req = R1 + R2 = 2 + 4 = 6 ohm, so I = V / Req = 6 / 6 = 1 A.
  • In parallel every branch has the full source voltage across it (6 V across R1 and across R2).
  • In parallel the branch currents add: I = I1 + I2 = 3 A + 1.5 A = 4.5 A.
  • Equivalent resistance in parallel: 1/Req = 1/R1 + 1/R2 = 1/2 + 1/4, so Req = 4/3 ohm…
  • An ammeter is connected in series and reads the same anywhere in a series loop; a voltmeter is connected across a part.
  • Opening one parallel branch stops only that branch; opening the main switch stops all current. Across an open switch…
  • Power P = V x I: the power the source supplies equals the total power used in the resistors.
  • Conventional current flows from the + terminal round the external circuit to the - terminal.
