In given diagram value of carbon resistor is 22 × 10 5 Ω ± 5 % . Write colour of first ring A .

According to colour code of carbon resistors, red stands for 2, yellow for 4, blue for 6 and silver stands for 5%.First and second band represents the first two significant figure of resistance. Third band represents the power raised to 10 in the value of resistance. Fourth band represents the tolerance. Given carbon resistor 22 × 10 5 Ω ± 5 % thus, Red is the colour of first ring A.

Write Kirchhoff's second law.

Kirchoff's Second Law states that the “net electromotive force around a closed circuit loop is equal to the sum of potential drops around the loop”. It is termed as Kirchoff's Loop Rule which is an outcome of an electrostatic field which is conservative. ∑ k = 1 n V k = 0
