Resistors

Choose 2 resistors and record treir individual ohm resistance measured with a multimeter:

Resistor 1 - 390 ohm Resistor 2 - 20 ohm

Put these two resistors together in series and calculate and then messure their combined value.

Calculated value in series R1 + R2 = 410 ohm

Measured value in series 409 ohm

Put the two resistors together in parallel calculate and then measure their combined value. Show workings.
