Question 13: Which of the following solutions do not conduct electricity?

a) Sodium hydroxide solution

b) Glucose solution

c) Acetic acid solution

d) Hydrochloric acid solution

Question 14: _______ gas gives an orange glow when electricity is passed through it. It is generally used in fluorescent lighting.

a) Hydrogen

b) Oxygen

c) Nitrogen

d) Neon

Question 15: What is the SI unit of electric current?

a) Newton

b) Joule

c) Ampere

d) Watt

Current = charge/time

= $\frac{1200}{6}=200$ ampere

=> Ans – (B)

Q= charge = I x T

V= potential difference

I= current

t= time

work done (W) = Q x V

=  I x t x V

= VIt
