## Calculate the combined resistance of resistors , Electrical Engineering

Assignment Help:

1.   Calculate the combined resistance of three resistors connected in series with resistance of 20 ohm, 30 ohm and 40 ohm? (to achieve a pass grade, solve problems with resistors in series)

2. Calculate the combined resistance of the resistors shown in this circuit: (to achieve a pass grade, solve problems with resistors in parallel)

3.   Calculate the combined resistance of the resistors shown in this circuit: (to achieve a pass grade, solve problems with resistors in series-parallel)

4.  Name two materials that are magnetic and two that are non-magnetic? (to achieve a pass grade, identify magnetic and non-magnetic material)

 Magnetic Non-magnetic
