You have two resistors with the same cross sectional area and resistivity. Resistor A has length L1 and resistor B has length L2
oee [108]

Answer:

Explanation:

Given

Resistor A has length L_1

and Resistor B has Length L_2

and Resistance is given by

R=\frac{\rho L}{A}

Considering \rhoand A to be constant thus

R_2>R_1 because L_2>L_1

(a)When they are connected in series

As the current in series is same and power is i^2R

therefore P_2>P_1 as R is greater for second resistor

(b)if they are connected in Parallel

In Parallel connection Voltage is same

P=\frac{V^2}{R}

resistance of 2 is greater than 1 thus Power delivered by 1 is greater than 2

What is described by the terms body-centered cubic and face-centered cubic?
Montano1993 [528]
In physical chemistry, the terms body-centered cubic  (BCC) and face-centered cubic (FCC) refer to the cubic crystal system of a solid. Each solid is made up simple building blocks called lattice units. There are different layouts of a lattice unit.

It is better understood using 3-D models shown in the picture. A BCC unit cell has one lattice point in the center, together with eight corner atoms which represents 1/8 of an atom. Therefore, there are 1+ 8(1/8) = 2 atoms in a BCC unit cell. On the other hand, a FCC unit cell is composed of half of an atom in each of its faces and 1/8 of an atom in its corners. Therefore, there are (1/2)6 + (1/8)8 = 4 atoms in a FCC unit cell.
