In parallel circuits total resistance will be less than the resistance of the least resistence device. HOW ? please helppp

Explanation:

Resistors can be connected in two ways;

1. Series connection

2. Parallel connection

When resistors are connected in series, the effective resistance is simply by adding up Rtotal = R1 + R2 + R3...

But when the are connected in parallel the effective resistance is simply 1/Rt = 1/R1 + 1/R2 + 1/R3

You can choose any value for your R1, R2 and R3 try it and see for yourself.

Good luck

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

this could be newton#'s law of cooling. the cooling curve is exponential
