Question

Calculate the resistance of a 2kW electric heater when connected to 220 volt source.

Answer 1

Answer:

given V= 220 V

2kw = 6.279 amp.

= 6.28 amp

according to ohms law

V = RI

R = V/I

R= 220 /6.28

R = 35.031 ohm

Explanation:

hope it helps uu

Answer 2

Answer:

The resistance of a 2kW electric heater when connected to 220 volt source is 24.20 ohm.

Explanation:

Given,

Current, I = 2 KW

2 KW = 9.09 amp

Voltage, V = 220 V

Resistance, R = ?

According to Ohm's law, we know that,

V = I × R

R = V / I

R = 220 / 9.09

R = 24.202420242 ohm

R = 24.2 ohm
