Question

plz help!! can't get through this numerical...!! science sucks!​

Answer 1

Answer:

a). ===4

b). ===20

resistance will decrease

Answer 2

Answer:

Explanation:1/Rp=1/4+1/4

=2/4

=1/2

Rp=2ohms

Rs=2+2

=4ohms

EFFECTIVE RESISTANCE:4OHMS

V=I×R

V=3×4

V=12

VOLTAGE:12V

COMPLETED ...........

Ops sry do u need 2 nd part also.???

So, V is directly proportional to I by OHMS LAW

when voltage is reduced to half current also gets reduced to half ........

Now it's fully completed
