Objective:

• How to make a circuit with the help of basic electronic components such as resistor in bread board.
•  How to use bread board.

Theory:

A bread board has many connections considered top row (+) ve, bottom row (-) ve. The remaining holes are connected vertically in columns of five holes with no link across. The gap across the horizontal centre of the bread board. When putting parts on bread board we must concentrate on connections, not their positions on the circuit diagrams, place the chip in the centre of the bread board and work round it pin by pin putting in all connections and components or each pin in turn. we have to keep the components that such a way that terminals are shorted.

Apparatus Table:

 SL.NO NAME OF COMPONENT QUANTITY MAKER’S NAME RANGE 1 BREAD BOARD 1 2 RESISTANCE 2 3 MULTIMETER 1

Observation Table:

 SL.NO INPUT VOLTAGE(VOLT) VALUE OF R1 (Ω) VALUE OF R2(Ω) CALCULATED VOLTAGE ACROSS R2 (VOLT) MEASERED VOLTAGE ACROSS R2 (VOLT) ERROR%=(C.V-M.V)/C.V*100 1 2

Calculation:

• I(R1+R2) =INPUT VOLTAGE
• To calculate voltage across R2 with respect to input voltage.

Conclusion:

1) There are some error in multimeter while measuring.

2) There are some instrumentation error.
