describe ohm law with examples
Here is your Answer:-
Ohm's Law
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I=V/R, where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.

7. A 500 g ball is about to roll off the edge of a 1. 5 m tall table. What is its current gravitational potential energy?
Answer: 7.35 Joules (7.35J)
Explanation:
Gravitational potential energy is defined to be the "stored" energy in the gravitational field. Since the force of gravity is conservative, the reference point for our zero potential does not matter. For simplicity, the zero reference point will be the floor which the table is sitting on. Gravitational potential energy is denoted as a capital 'U' and is defined to be:
[tex]U=mgh[/tex]
The 'm' is the mass, the 'g' is the acceleration due to the gravitational field, and the 'h' is the vertical height from the reference point. Plugging in the given values, you get:
[tex]U=(0.5kg)(9.8m/s^2)(1.5m)[/tex]
[tex]U=7.35J[/tex]
The SI units for mass is always the kilogram. So, you need to convert the grams into kilograms using the conversion factor of 1000g = 1kg.
rearrange the equation d=vt-1/2at^2 to find v
Explanation:
This is the formula for the change in distance (δx) of an object moving with constant acceleration (a) and initial velocity (v), one of the standard Equations of motion. To solve for t first rearrange
12at2+vt−δx=0
then apply the formula for solving a Quadratic equation if our equation is At2+Bt+C=0 then the solution is
t=−B±B2−4AC√2A,
here A=12a, B=v, C=−δx so plugging these in the formula gives
t=−v±✓v2−4(12a)(−δx)√2(12a) (Apply quandriatic equation)
simplifying
t=−v±v2+2aδx√a.
Note how there are two possible solutions one corresponding to the + and one to the -. Sometimes one of these will give a negative time, so you may want to eliminate that. Indeed if δx>0, v>0 and a>0 we only want the positive solution. In other cases you may want to consider both solutions, for instance if we thow a ball up in the air the initial velocity is positive and the acceleration is negative, it will pass a fixed height above your head twice, once on the way up and once on the way down.

Explanation:
The magnitude of the electric field between two parallel charged plates is 200. An electron moves to the negative plate 5. 0 cm away. Two horizontal parallel plates have equally spaced vectors going from the top plate to the bottom plate labeled E and the plates are spaced a distance d apart. There is a negatively charged sphere is near the positively charged plate and a second is directly below and near the negatively charged plate. The two charged particles are connected by a dashed line vector point from the top to the bottom one. Find the electric potential difference and the work. Recall the charge of an electron is 1. 602 × 10–19 C. ΔV = V Round work to one decimal. W = × 10–18 J.
The potential difference between the two ends of the circuit is the electric potential difference. The electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.
What is an electric field?An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
The given data in the problem is given by;
E is the electric field = (200 N/C)
d is the distance = 5.0 cm.=0.05 m
Q is the charge of electrons= 1.602 x 10^-19 C
The formula for electric potential is given by;
[tex]\rm V=Ed[/tex]
[tex]\rm V=Ed \\\\ \rm V=200 \times 0.05 \\\\ \rm V= 10 \frac{Nm}{C} = 10 \frac{J}{C} = 10 V.[/tex]
The work is defined as the product of the potential difference and charge of an electron.
[tex]\rm W= 10 \times 1.602 x 10^{-19} \\\\\ \rm W= 1.6 x 10^{-18 }J[/tex]
Hence the electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.

KE = 1/2 mv²
v = 10 km/h = 2.78 m/s
v = 20 km/h = 5.56 m/s
10 = 1/2 m . 2.78²
m = 2.59 kg
