Physics 2 Quiz Review 2

zero

A proton is at rest in side the a magnetic field, the force is

charge.

Ampere-hour (A.hr) is the unit of

negative.

An electron is moving along positive x-axis in side a magnetic field that is in the positive Y-axis

zero

An electron is moving parallel to the direction of magnetic field, the force on electron is

increase temperature and resistor.

If the temperature changes the resistivity will

positive.

If the traversal of the circuit is opposite direction of current the potential difference is

same equation.

If you move in the same or opposite direction of current the loop law equation will be

split or parallel is zero series remain same.

In a parallel and series connection the current will be

parallel voltage is constant series. All of the potential is same of the voltage of all potential voltage.

In a series and parallel connection the voltage will be

domain.

In ferromagnetic material the magnetization occur by ailing the

directly proportional to current squared.

In joules Heat expression P = I2R, therefore power is

current and potential difference.

In ohms law current is

series increase, parallel decrease.

In order to increase or decrease the resistance, the resistor will be connected

R=SI/a

Is the resistivity of a material

energy.

KWH is the unit of

current and voltage

Ohms law is the relationship between

orbiting electron in the atom.

The core of magnetic field from

Metal temperature increases, drift velocity decrease, semi-conductor temperature increases more than N, which is the number of turns. VD=Increase, I= Decrease, Resistance=Increase.

The expression of current through a metal is given by I = nqvdA, if the temperature increases what happen?

number of turns increase while length decrease.

The magnetic field produce by a solenoid, B = μoNI/L, if the current, I is remain constant, the magnetic field will increase

anything comes will leave also in a case close surface 0 to 180.

The magnetic flux through any closed surface is zero implies

spiral of it is 0 or 90 circle if its not 90.

The path of a charge particle is moving in side a magnetic field, where the angle between then is not 90 degree,

same diameter, length; different diameter, length.

Two different metal wire of same diameter and length, the resistance will be different because

seconds

What is the unit of RC ( where R is the resistance & C is the capacitance)

A=Ampere; V=Volt

What is unit of current and potential difference?

magnetic field.

Which one does not have mono-pole?
