find voltage and current r1 60 ohms r225 ohms r3 40 ohms r4
find voltage and current.
r1= 60 ohms
r2=25 ohms
r3 = 40 ohms
r4 = 20 ohms
r5 = 55 ohms
Solution
V=IR
in order to calculate current ,the following formula is used
I=V/R
V=100
1)R=60 ohms
current=100/60 =1.66 amperes
2)R=25 ohms
current=100/25 =4 amperes
3)R=40 ohms
current= 100/40 =2.5 amperes
4)R=20 ohms
current=100/20 =5 amperes
5)R=55 ohms
current= 100/55 =1.81 amperes
For parallel resistors formula is Requa=R1R2/R1+R2
FOR SERIES RESISTANCE FORMULA IS Requ=R1+R2
total rersistance in the given circuit is 88.57 ohms
V=IR
1)60 ohms
V=IR
=1.66(88.57)=147 VOLTS
2)25 ohms
V=IR
=4(88.57)=354.28 VOLTS
3)40 0HMS
=2.5(88.57)=221.425 VOLTS
4)20 OHMS
=5(88.57)=442.85 VOLTS
5)55 OHMS
=1.81(88.57)=160.317 volts
