1. A dry cell consists of a zinc container whose base acts as the negative electrode. The carbon rod placed at the centre with a brass cap acts as the positive electrode. This is surrounded by a mixture of manganese dioxide and charcoal in a muslin bag. The electrolyte uses is a moist paste of ammonium chloride.

2.

The construction of an electric bell consists of a gong, an electromagnet, a soft iron rod and a contact screw. The working of an electric bell: When the current passes through the electromagnet, it becomes magnetized which helps to attract the armature and after this the hammer raids and attract the armeture.
