ENGINEERING MEASUREMENTS LAB REPORT
INTRODUCTION
Basic overview
There are common household electrical circuits which mainly operate on the Ohm's law. Many
of these components are connected in parallel. The electric circuits in these devices are
connected to the power source and draw from the source in different amounts depending on the
value of the resistors in the circuit design. The electric components have a power supply and
loads which get the supply. Hence, there is a direct proportionality between the potential
difference of a circuit and the resistance component.
The Ohm's law is given as
V =IR
The use of series and parallel connections is applied to light the small rooms and very huge
rooms. The Kirchhoff’s current and voltage laws are used in the parallel connections while the
summation expressions are used in the series connections. The resistors are measured using color
codes or measured using a multimeter,
EXPERIMENT
TASK 1: FAMILIARIZATION OF INSTRUMENTS AND COMPONENTS
Aim:
1

(i) To determine the functions and purpose of the series and parallel components in the
circuit design.
Components and Instruments
(i) DC generator (Power supply)
(ii) Micrometer
(iii) Resistors (series/parallel unit)
(iv) Ammeter and voltmeter
Discussion
The DC generator is included in the circuit as the point of power supply. It provides 20 volts to
the channel. The micrometer is used in the measurement of lengths. The resistors are used to give
the resistance component in the loop. The ammeter measures the current flowing through the
loop while the voltmeter measures the potential difference across each element on the channel.
TASK 2: SERIES AND PARALLEL CIRCUITS
Aim
(i) To determine the behavior of circuits and current flow in series and parallel
connections.
