# Kalyani's Physics Flashback ## 64. Calculate the equivalent resistance between P and Q in the following circuit, each resistance is of 10 Ω. ![]() 2019 ## 65. If the electric current in a conductor of uniform cross section is increased by 20%, the drift velocity of electrons in the conductor. * (i) increases by 20% * (iii) decreases by 20% * (ii) increases by 40% * (iv) decreases by 40% ## 66. How will you connect three resistors R₁ = 1Ω, R₂ = 2Ω and R₃ = 2Ω to get an equivalent resistance of 2Ω? Draw the related circuit diagram? ANSWERS
