The result of the division is a current, measured in Ampere. Since the voltage is AC, the current will also be AC.
we have this 1/Re = (1/R1)+(1/R2) for calculating the effective resistance when resistances are connected in parallel so the answer would be Re =( 70*30) / (70+ 30) = 21 ohms
As you have not supplied any information, other than the resistance of the individual resistors, there is no way in which your question can be answered.
The total DC resistance is (33+47) = 80 ohms.The total reactance is j(60+30) = j90 ohms.The total impedance of the string is [ 80 + j90 ] ohms,= 120.4 ohms at a phase angle of 48.37 degrees (both numbers rounded).
Set a Volt-Ohm meter to Ohms and put the two leads from meter across the fuse. One on each end where the metal is located. The meter should read zero ohms if the fuse is NOT blown.
Ohm's law: voltage is current times resistance 0.03 amperes times 1000 ohms = 30 volts.
For an end-result of 10 ohms, you can have 1 resistance of 10 ohms, or 2 parallel resistance of 20 ohms each, or 3 resistances of 30 ohms each, etc.

Ohm's Law: Current = Voltage divided by resistance90 volts divided by 30 ohms = 3 amperesBe careful if you try this, it is also 270 watts, so the resistor will get very, very hot. Also, since everything has a temperature coefficient, do not expect the resistance when hot to be the same as the resistance when cold.
30 ohms
When any number is divided by a negative number the result is negative. So, 120 / -4 = -30
810/30=27
30 micro ohms

No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
