Question

Three resistors =Ω, =and = are connected asshown in figure. Through the resistor 10Ω a current of 1A is flowing

(i) What is the potential difference across and across AB? 2

(ii) What is the current through ? 2

(iii) The total resistance between A and B is

a. 5Ω b. 10Ω c. 20Ω d. 40Ω

Answer 1

Answer:

1) 10v

2)0.5A

3)20 ohms

Explanation:

Total equivalent resistance 10+20/2=20 ohms

current through 20ohms= 1/2=0.5amperes

voltage across 20ohms= current*resistance=0.5*20=10v
