Calculation of Current Taken by Lamps


Given Data:


  • Four lamps each of 100W, 200V

  • Connected across a supply of 200V



Formula:

Current (I) = Power (P) / Voltage (V)


Calculation:


  • Total power consumed by lamps = 4 x 100W = 400W

  • As each lamp is of 200V, they will consume 2A of current individually using the formula I = P/V

  • Therefore, the total current consumed by four lamps will be 4 x 2A = 8A



Answer:

The current taken by the lamps when connected across a supply of 200V is 8A.
