According to Ohm’s law, the ratio of voltage to current in a conductor is constant.
Answer: Option A
<u>Explanation:</u>
Ohm's law defines that an electric current flowing through the conductor between two ends is directly proportionate to the voltage at these two points. The introduction of a constant proportionality, resistance, gives a simple mathematical equation describing this relationship. Particularly, Ohm's law also mentions that R is constant in this respect, i.e. not dependent on the current.

Where,
I is the current conduction in amperes
V is the voltage calculated by the conductor in volts
R is the conductor’s resistance in ohms.
#1
length of one complete wave shape is known as wavelength
#2
Frequency is defined as number of oscillations per second or number of waves passing through a point in one second.
#3
One Time period is the time to cover one complete wavelength distance by the wave
#4
relation between time period and frequency is given as

#5
Time period of simple pendulum is given as

so it depends on length of pendulum and acceleration due to gravity
#6
amplitude of the wave is the height above the axis to which particle can attain its maximum position or its maximum height on y axis is amplitude
