1.	Fill in the blanks: (a) Current does not flow in an _______ electric circuit. (b) Electric bell is based on the _______ effect of current. (c) ________ is an electric component which is used to open or close an electric circuit. (d) S.I. unit of speed is __________. (e) Distances between two cities are measured in_________.
Answer» ong>Answer: $\huge\underline\mathbb\blue{Answer:-}$ 1-(a)Current doesn't flow in an opened circuit. Explanation:- because the current is stopped where the switch is started or ended (b)heating effect Explanation:- because the collision of positive and negative charges produce heat (c)switch which is mainly MADE from Bakelite (d)metre PER second(m/s) Explanation:- the S.I. unit is m/s,but the most commonly used unit in our life is Kilometer per HOUR(km/h). In UK and USA the unit is miles per hour[mph) (e)kilometers Explanation:- because the DISTANCE may be too long between cities so it can't be measure in meter so we usually uses kilometers or sometimes miles

ong>Answer:

$\huge\underline\mathbb\blue{Answer:-}$

1-(a)Current doesn't flow in an opened circuit.

because the current is stopped where the switch is started or ended

(b)heating effect

because the collision of positive and negative charges produce heat

(c)switch

which is mainly MADE from Bakelite

(d)metre PER second(m/s)

the S.I. unit is m/s,but the most commonly used unit in our life is Kilometer per HOUR(km/h). In UK and USA the unit is miles per hour[mph)

(e)kilometers

because the DISTANCE may be too long between cities so it can't be measure in meter so we usually uses kilometers or sometimes miles
