Which of the following statements about Ohm’s Law is true?
2 answers:
Answer:
To increase the current, decrease the resistance.
Explanation:
Ohm's law relates the current, resistance and the voltage. This law states that "the potential difference or the voltage across the ends of any conductor is related directly to the current flowing through it". The mathematical relationship is given by :
V = I × R
Where
R = resistance of the circuit
The current is inversely proportional to the resistance of the circuit. Hence, the correct statement about the Ohm's law is (a) " To increase the current, decrease the resistance".

Answer: (a) and (b) => check attached file.
(c). Picture (a) and (b) will both remain the same.
Explanation:
IMPORTANT: The solution to the question (a) and (b) that is (a) Draw a neat snapshot mode labeled vector picture of the wave. (b) Draw a neat movie mode labeled vector picture of the wave is there in the ATTACHED FILE/PICTURE.
It is also worthy of note to know that in anything Electromagnetic wave, the magnetic field, the Electric Field and their direction of propagation are perpendicular to each other.
Therefore, knowing the fact above we can say that in yellow light, the magnetic field is in the y-direction and the Electric Field is in the z-direction.
Hence, the solution to option C is given below;
(C).If the wave were to represent blue light instead of yellow light, picture (a) will remain the same because both light are Electromagnetic wave, although the wavelength will have to change. Picture (b) will also remain the same because they are both Electromagnetic waves and possess similar properties.
