Roshan describes the basic parts of an electric circuit using a shower as a model.
The water pipe represents the wire which enables the power to go from one point to another.
An instance of a pipe it enables the water to spill out of a side to another.
This is the way it is looked at.
Answer:
The unit of resistance is ohm. 1 ohm is defined as the amount of resistance encountered by 1amp of current moving under potential difference of 1 volt.
.
(2) From Ohm's Law
V = IR
or current
I = V/R = 12V / 6ohms = 2 amps
.
(3) Flow of electrons is always opposite to the direction of flow of conventional current.
.
(4) we know that, I = q/t
or amount of charge
q = I.t = 40A x (30x60s)
so, q = 72000 C
.
(5) A cell is a fundamental or basic device which converts chemical energy to electrical energy, it is a single unit. A battery on the other hand is composed of a number of cells.
.
(6) Ohm’s law states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) across the ends of a conductor, provided physical conditions of the conductor such as temperature, mechanical strain etc. are kept constant.
V ∝ I
On removing the proportionality signs we get:
V = IR
Where R is the resistance and is measured in SI unit called ohm(?).
