Question

A battery of 10v and internal resistance 4ohm is connected to a parallel combination of two resistors of resistances 10 ohm and 15ohm calculate the terminal voltage of the battery

Answer 1

Given,

A battery of 10v and internal resistance 4ohm is connected to a parallel combination of two resistors of resistances 10 ohm and 15ohm,

R+r= E/I

R+4 = 10/0.5

R+4=20

R= 20–4

R= 16 Ohms
