Question

2 resistors with resistance 10 ohm and 15 ohm are to be connected to a battery of 5v so as to obtain a)maximum current b)minimum current 1)how will you connect the resistance in each case? 2)calculate the strength of total current in the 2 cases.

Answer 1

Answer:

answers given below

Explanation:

given resistors 10 ohm and 15 ohm

maximum current means low resistance therefore parallel circuit

1/ Rp= 1/r1+ 1/r2....

1/Rp= 1/10+ 1/15

1/Rp= 5/30

1/Rp= 1/6

Rp= 6 ohms

current

V= IR

5v= I x 6

l= 5/6 ampere

I= 0.833 A

Minimum current means more resistance therefore series circuit

Rs= r1+ r2...

Rs= 10+15

rs= 25 ohms

current

V= IR

5v= I x 25

I= 1/5 ampere

I= 0.2 A
