Experiment no.1 (resistors)










NOTE:
In a series circuit resistance is added together to giving a prpportional decrease in the flow of current ,in addtion a lower resistance reading.

resistance in a parallel circuit
-


Working:

Resistor 1 : 98900 ohms

Resistor 2 : 389 ohms

Both in series :
calculated : 99289 ohms

measured : 99200 ohms

Both in parallel :

calculated : 387.48 ohms




measured : 388 ohms

  2. in a series circuit the resistance is added together increasing the total resistance, while ion a parallel circuit the total resistance is lower than the smallest resistor in the circuit
