Color of third band of a coded resistor is Brown.
What is Resistance:
- Resistance is a measure of the opposition to current flow in an electrical circuit.
- Resistance is measured in ohms, omega (Ω)
The color code specify the resistance value, the tolerance, and sometimes the reliability or failure rate.
How to identify resistor's color codes:
- Look at the resistor so the group of 3 or 4 color bands are on the left side
- Read the color bands from left to right.
- Read the color on the last color band, which is farthest right.
- compare the colors to the resistance code table
Here,
the value of resistance is 2.3x10^2 Ω
R = 23x10^1 Ω
here power of 10 is 1
so, the color of third band of a color coded resistor will be related to number 1
Hence,
color of third band of a coded resistor is Brown.

Answer:
the answer would be B your welcome
Explanation:
The answer is D. more quickly when heat is added to them
Answer:
a) 20.29N
b) 19.43N
c) 15N
Explanation:
To find the magnitude of the resultant vectors you first calculate the components of the vector for the angle in between them, next, you sum the x and y component, and finally, you calculate the magnitude.
In all these calculations you can asume that one of the vectors coincides with the x-axis.
a)
b)
c)
Answer : The energy of one photon of hydrogen atom is,
Explanation :
First we have to calculate the wavelength of hydrogen atom.
Using Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant = 10973731.6 m⁻¹
= Higher energy level = 3
= Lower energy level = 2
Putting the values, in above equation, we get:
Now we have to calculate the energy.
where,
h = Planck's constant =
c = speed of light =
= wavelength =
Putting the values, in this formula, we get:
Therefore, the energy of one photon of hydrogen atom is,
