Answer:
Ohm's Law. The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

Answer:
0.005 V
Explanation:
We are given that
Initial circumference of circular loop=C=165 cm
Rate of circumference,
Magnetic field,B=0.5 T
We have to find the induced emf at time t=9 s
We know that induced amf,E=
Area of circular coil,A=

Circumference of circular coil,C=



Radius of coil at time t=9 s


E=
Magnitude of induced emf=0.005 V
Answer:
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.
