Question

1.

(1)The word electricity derives its origin from the
Greek word ..............
(2)When a number of resistances are connected in
series, the equivalent resistance is ...
any individual resistance.​

Answer 1

Answer:

1.(elektron) which means Amber.

2. Greater or maximum

Explanation:

1) The word electricity is derived from word elektron which means amber in latin.

The amber is a material which can be charged by rubbing with wool or fur.

2) When a number of resistance is added in series the equivalent resistance is maximum than any individual resistance.

Series arrangement :- when the resistance is joined end by end in a circuit then it is said to be the resistance are arranged in series arrangement.

The equivalent resistance in series arrangement is given by formula :-

$\boxed{\sf\red{Re = R1 + R2 + R3........Rn}}$

where R is resitors.
