Question

What is the resistance of an electric arc lamp if the lamp was 20 Amp
when connected to a 220 V line

Answer 1

Explanation:

V = IR

R = V / I

R = 220/20 = 22/2 = 11 ओम

Answer 2

Answer:

11 ohm

Explanation:

according to Ohm's law Resistance =Potential / Current that is, V/I therefore 220/20 =11 ohm
