I don't understand this, sorry!
Answer : The correct options are, V=IR, I=V/R and R=V/I
Explanation :
Ohm's law : It is defined as an electric current is directly proportional to voltage and inversely proportional to resistance.
Formula of Ohm's law :
Or,
or,
where,
R = resistance of a circuit
V = voltage of circuit
I = current flowing in a circuit
Hence, the correct options are, V=IR, I=V/R and R=V/I
Answer:
Frequency,
Explanation:
Wavelength of a light wave is 450 nm. It is required to find the frequency of this light wave. The speed of light is given by c. So,
f is the frequency of this light
So, the frequency of this light is .
The answer is "b" a circuit.
