Question

give the answer hurry pliz​

Answer 1

Explanation:

1/r= 1/5+1/10+1/30

1/r= (6+3+1)/30

1/r= 10/30

r= 30/10=3Ω

v= 6v

current I= v/r

= 6/3

= 2 amp

a) value of current through the 30Ω resistor is-

2*30/(5+10+30)

= 60/45

= 1.33 amp

b) total resistance-

1/r= 1/5+1/10+1/30

1/r= (6+3+1)/30

1/r= 10/30

r= 30/10=3Ω
