Answer:
4 A
Explanation:
Firstly we need to calculate the equivalent resistance. Since, two resistors of 6 connected in parallel, so equivalent resistance will be given by,
1/R = 1/R1 + 1/R2
1/R = (1/6 + 1/6) Ω
1/R = (1 + 1)/6 Ω
1/R = 2/6 Ω
R = 6/2 Ω
<u>R = 3 Ω</u>
We know that,
V = IR
- <em>V</em> denotes p.d (12V)
- <em>I</em> denotes current
- <em>R</em> denotes resistance (3 Ω)
12 = I × 3
12 ÷ 3 = I
<u>4 Ampere = I</u>
6 V drop occurs across the 6 ohm resistor in the parallel circuit diagram. The correct answer is C.
Since this parallel combination is connected with a cell, the potential difference through each resistor will be 6 volts. Now using I=V/R,
Current through 3 ohm resistor = 6/3 = 2 V
Current through 6 ohm resistor = 6/6 = 1 V
And the total current will be the sum of individual current in each resistor using Kirchoff’s junction law, Total current = 3 ampere
Since it is parallel combination the current passing across two resistors can differ but the voltage drop will remain the same.

Answer:
A medium in which speed of light is more is known as optically rarer medium and a medium in which speed of light is less is said to be optically denser medium. For example in air and water, air is raer and water is a denser medium.
