Question

An electric heatet of resistence 500 ohm is connected to the main supply of 220v and current flow in the heater for 1 hour . Calculate the amount of heat produced in the heater

Answer 1

voltage RMS = 220 V
current rms = voltage/resistance = 220/500 = 0.44 A
heat developed = power loss = I²R = (0.44)².500 = 96.8 Joules.

Answer 2

Answer:

voltage RMS = 220 v

voltage RMS = 220 v current RMS = v/R

voltage RMS = 220 v current RMS = v/R220/500 = 0.44 A

voltage RMS = 220 v current RMS = v/R220/500 = 0.44 A power loss = I^2R = (0.44).500

voltage RMS = 220 v current RMS = v/R220/500 = 0.44 A power loss = I^2R = (0.44).500= 96.8 j
