In series, R_total = R1 + R2 = 4Ω + 6Ω = 10Ω.

In a series circuit, total resistance (R_total) is the sum of individual resistances: R_total = R1 + R2 + R3 = 2Ω + 3Ω + 5Ω = 10Ω.

In series, R_eq = R1 + R2 = 4Ω + 4Ω = 8Ω.

For parallel resistors, 1/R_eq = 1/R1 + 1/R2 = 1/4 + 1/6. Finding a common denominator gives R_eq = 2.4Ω.

In series, total resistance R = R1 + R2 = 4 Ω + 6 Ω = 10 Ω.

The atomic radius increases as you move down the alkali metal group due to the addition of electron shells.

The reactivity of alkali metals increases down the group due to the decrease in ionization energy.

The Tyndall effect is the scattering of light by colloidal particles, making the path of the light visible.

In reverse bias, a diode exhibits a very small reverse saturation current until breakdown occurs.

The typical forward voltage drop across a silicon diode is approximately 0.7 V.

The diamond structure is based on a face-centered cubic (FCC) unit cell with a specific arrangement of carbon atoms.

The diamond structure is classified as a face-centered cubic (FCC) lattice with a basis of two carbon atoms.

Diamond has a face-centered cubic (FCC) structure with a complex arrangement of carbon atoms.

Magnesium has a valency of 2, as it can lose two electrons.

Oxygen has a valency of 2, as it needs two electrons to complete its outer shell.

(1 + i)(1 - i) = 1^2 - i^2 = 1 - (-1) = 1 + 1 = 2.

Using BODMAS: (2 + 3) = 5 and (4 - 1) = 3, so 5 × 3 = 15.

(2 + 3) × 4 = 5 × 4 = 20.
