Explanation / Answer

An electrical component has two resistances of 15 omegasign and 25 omega sign connected in parallel. a). What is the total resistance of the component?-------omegasign
when they are connected in parallel
effective resistance=R1*R2/R1+R2=15*25/40=9.375omega sign
b). If connected to a 120-V source, how much current wouldthere be in each resistor?          15 omegasign resistor.-----A
120/9.375=total current=12.8A
current in 15 ohm=12.8*25/40=8A
         25 omegasign resistor.------A
current in 25 ohm=12.8-8=4.8A
