definition of ohms law and it's formula
Answers
Answer:
Answer:
The frequency of radio waves of wavelength 150 m is 2 MHz.
Given:
We're given with the velocity of electromagnetic wave in free space is 3 \times {10}^{8}3×10
8
m/s. Wave length of radio waves is 150 m.
To find:
We are supposed to find out the frequency of radio waves with wave length 150m.
Solution:
Apply the concept of frequency of radio waves.
It is given by,
\implies \rm\dfrac{v}{ \lambda}⟹
λ
v
\implies \rm \dfrac{3 \times {10}^{8} }{150}⟹
150
3×10
8
\implies \rm\dfrac{3 \times {10}^{7} }{15}⟹
15
3×10
7
\implies \rm\dfrac{ {10}^{7} }{5}⟹
5
10
7
\implies \rm2 \times {10}^{6} \: Hz⟹2×10
6
Hz
\implies \rm2 \: MHz⟹2MHz
So, the final answer is:
\dag \: \boxed{ \bf{2 \: MHz}}†
2MHz
Answer:
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.
