Question

in an electric heater draws a current of 5 A when connected to 440v mains . calculate the resistance

Answer 1

Potential difference = V = 440 v
Current = I = 5A
Resistance = R = ?

according to ohm's law
V = IR
V/I = R
440/5 = R
88 ohm = R

resistance is 88 ohm

Answer 2

  data:
     I = 5A
    V = 44v

    required:
    R=?

    solution:
    according to formula

       V= IR

    R=   V
         ---------
            I

R= 440
     ------
       5

R= 88 ohm

Result: The resistance is 88 ohm......
