LABORATORY EXPERIMENTS

11.1 EXPERIMENT 1: BASIC ELECTRICAL CIRCUIT
COMPONENTS AND KIRCHOFF’S VOLTAGE AND
CURRENT LAWS

Objectives

1. Confirm by measurements the input–output behavior of basic electrical and elec-
tronic circuit components: resistance measurement, capacitance measurement, diode
test.
2. Confirm Kirchoff’s voltage law and current law in a simple DC circuit with resistors.
3. Build a voltage divider circuit and verify the predicted results from Kirchoff’s laws
by measurement.
4. Build a current divider circuit and verify the predicted results from Kirchoff’s laws
by measurement.
5. Build an RC circuit and an RL circuit, measure their input output voltage relationships,
and compare the differences between their responses. Measure the R, C, and L
components in the RC and RL circuits.

Theory
The passive components make up the main building blocks of electrical circuits: resistor,
capacitor, and inductor. The input–output relationship of these “ideal” components are as
follows.
An “ideal” resistor has the following current–voltage relationship, also called Ohm’s
Law,

V (t) = R ⋅ i(t) (11.1)
