Question

Figure below shows a3ohm resistor and a6ohm resistor connecte in parallel across a1.5Vcell calculate tha curret in :(a)3ohm resistor (b) 6ohm resistor, (c) the cell, (d) calculte the resistance of the paralld combination

Answer 1

Answer:

a) 0.5

b. 0.25

c) 0.75

d) 2 ohms

Explanation:

a) r=3ohms

v=1.5v

so from ohms law

I=v/r

=1.5/3

=0.5 A

b) r=6ohms

v=1.5v

so from ohms law

I=v/r

=1.5/6

=0.25 A

c)a) r=2ohms

v=1.5v

so from ohms law

I=v/r

=1.5/2

=0.75 A

d) R1=3ohm

R2=6ohms

so, 1/req =1/R1+1/R2

=1/3+1/6

= 2+1/6

=3/6=1/2

so, req=2 ohms
