v of what? v across what? v measured from what 2 points? v across the coils? v across the resistor? v across the coils and resistor? v across the battery? v across the battery and coils? v across the battery and resistor? or are you asking what v stands for? v stands for voltage.
V(ripple)= V(rms) / V (DC)
Since resistance is inversely proportional to the cross-sectional area of a wire, thicker the wire - lesser the resistance and vice-versa. Now, according to Joule's law of heating, H = I^2 R t; i.e. H (Heat) is directly proportional to the square of I (Current), R(Resistance) and t (time). Whereas, according to Ohm's law, V=IR; i.e. V (Potential difference) is directly proportional to I (Current) and R (Resistance) Comparing both the formulas, we can conclude that H (Heat) needs more Current; I. [H=I^2 R t] Therefore, thicker wire. Hence, the cooker needs a thicker wire while a table light needs a comparatively thinner wire.

The 3 basic formulas for Ohm's Law are :V=IRI=V/RR=V/I

The answer is 57, because 7 times 57 is 399.
