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
The magnitude of the quantity and its direction.
Given that the arc length is:
s = ∫ √[1² + (dy/dx)²] dx
<span>So arc length between the two points is then: </span>
<span>s = 2*20sinh(x/20)
= 40sinh(x/20) </span>
<span>The straight distance between the two points is : d = 2x </span>
<span>So, x = d/2.
= 40/2
= 20 m </span>
<span>Plug this into the arc length equation to get:
s = 40sinh[20/20)]
=40* ½ (e - 1/e) </span>
<span> = 47 m</span>
There is a relationship between energy, current, voltage and time. The formula to be used is written below:
E = IVt,
where
I is the current in amperes
V is voltage in volts
t is the time in seconds
Substituting the values,
E = (0.5 A)(120 V)(60 s)
<em>E = 3,600 J</em>
