Question

an electric heater of resistance of 3 metre Omh supplied with 0.5 A current calculate the power consumed by electric heaters​

Answer 1

Explanation:

P is equals to I square R

p=(0.5)(0.5)(3)

p=(0.25)(3)

p=0.77 w

Answer 2

Answer:

resistance =3 ohm

current =0.5 A

power =work /time

so P=W/t

W=I2Rt

so P=I2R

so. power=(0.5*0.5*3)watt

=(0.25*3)watt

= 0.75 watt

Explanation:

as per me unit of resistance is ohm not meter ohm. ohm meter is the unit of specific resistance.
