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.
