if two heater of rating 1KW,200v are connected in series 100v
supply what will be the power taken



if two heater of rating 1KW,200v are connected in series 100v supply what will be the power taken ..

Answer / wareagle

normal amperage = 1000/200 = 5 amps
therefore R = E/I 200/5 = 40 ohms
heater in series resistance = 80 ohms
voltage = 100 volts
amps = 100/80 = 1.25 amps
watts = VA = 100 x 1.25 = 125 watts
