Experiment N0. 1 CONSTRUCTION & OPERATION OF SIMPLE ELECTRICAL CIRCUITS OBJECTIVE: The experiment is to acquaint the students with some simple circuits and to make them familiar with diagram reading, drawing and wiring with the help of different types of switches (SPST- Single pole single throw, SPDT single pole double throw, DPST Double pole single throw, DPDT Double pole Double throw) that will be frequently encountered in different experiments. INSTRUCTIONS: Read the following procedure carefullyr and draw the circuit diagrams accordingly in the space allotted for each procedure and then implement it practically. Your report must contain neat diagrams of the circuits. APPARATUS: 1) Two lamp boards (220V, 100w) 2) Two SPST, two SPDT, one DPDT switch. PROCEDURE: 1. Connect an electric lamp so that it may be operated from a 2201? ac supply using an SPST switch. . / 1 s 230 Volt L AC Supply 2. Connect a lamp so that it may be operated by either of two SPST switches. ._/_/ f SI 32 23 0 Volt AC Supply 4 (a) 3. Connect two lamps so that either may be operated from a common source by its own switch
