What is the potential difference between X and Y in the diagram above if the battery is of negligible internal resistance

Total resistance at XY=1/(1/2+1/3)

= 1/(5/6)

= 6/5 or 1.2 Ohms

Total resistance= 1.2+0.8=2 Ohms

Value of Current flowing through circuit = 5/2 =2.5A

Potential difference across XY = 2.5×1.2

= 3V

WAEC1995: What is th p.d between X and Y in the diagram below if the battery is ofnegligible internal resistance? calculate the current in the 3 ohms resistor

Difference in the p.d v1-v2= 5v-2v
=3v

To calculate the current in 3ohms resistor
remember the total internal resistance is 2
and resistor is 3 and in emf remember R+r R=3 and r=2 =3+2=5
also
note V=IR
5/5= 5i/5
I=1.0ampere
