Draw the loci
`r = a `

Draw the images P' , Q' and R' of the point P, Q and R respectively in the line n (Fig . 9. 18). Join P' Q' and Q' R' to form an angle P' Q' R' Measure angle PQR and angle P' Q' R' . Are the two angles equal ?

A battery of emf 3V and internal resistance r is connected in series with a resistor of 55 Omega through an ammeter of resistance 1 Omega . The ammeter reads 50 mA. Draw the circuit diagram and calculate the value of r.
