, Electric circuits with resistors in series and parallel – measuring potential
difference and current.




Step 1: Identify a problem and develop a question.


What is the effect of resistors connected in series and parallel according to potential
difference (V) and current (A) measured across the circuit?


Step 2: Hypothesis


Potential difference of resistors connected in series divide across the circuit but
Current is the same and potential difference of resistors connected in parallel is the
same across the circuit but current divide.


Step 3: Design an Experiment


Apparatus needed


 Multi-meter
 Resistors
 Supply voltage
 Wires
 Connecting board
 Wire stripper
 Side cutter
 Nuts and washers


Procedure


Design and wire a circuit with resistors connected in series and supply the circuit
with 125V. Use a multi-meter to test or measure the potential difference (v) and
current (A) across the circuit and record the findings in a table form.
