← A metre bridge has a 14 Ω coil on its left and a 10 Ω coil on its right. Another 15 Ω coil is now connected across the right-hand coil. Find the new balance point, measured from the left end of the wire.The wire current of a potentiometer is kept steady. A cell of 3.9 V has its null point at 520 cm, and an unknown cell has its null point at 360 cm. What is the unknown emf? →
