While touching the Van de Graaff generator, why does your hair fly up as it starts charging?
because the opposite charge is transferred to the hair
because the charge of the generator is transferred to the hair
because the charge of the hair is transferred to the generator
because the opposite charge of the hair is transferred to the generator
Which of the following best describes electric potential energy?
charge per unit distance
electric potential per unit charge
the amount of work needed to move a unit charge
the capacity for doing work which arises from position or configuration
Which of the following describes a parallel connection of capacitors?
The total charge is equal to the individual charges.
Total voltage is equal to the sum of the voltage drop in each capacitor.
The equivalent capacitance is equal to the sum of the individual capacitance.
The reciprocal of the equivalent capacitance is equal to the sum of the reciprocal individual.
Increasing the voltage across a two-plate capacitor will produce what effect on the capacitor?
decrease charge
increase charge
decrease capacitance
increase capacitance
What will happen to the charges and electric field when inserted a dielectric material in a capacitor?
The charges and electric field increase.
The charges and electric field decrease.
The charges increases and the electric field remain the same.
The charges remain the same and the electric field decreases.
Which of the following types of electric current flows in one direction ONLY?
alternating current
electron current
direct current
steady current
Why is copper wire commonly used for electrical wirings?
because of higher resistivity
because of higher conductivity
because it is a unique conductor
because it is more common than nichrome wire
Which of the following describes both electromotive force and potential difference?
Their symbol is ΔV.
Their SI unit is volts.
They transmit current in and out of the cell.
They cause electromagnetic field and gravity.
Which of the following best describes Ohm’s Law?
As the voltage increases, the current decreases.
The higher the resistance, the lower the voltage.
The higher the resistance, the higher the current.
As the voltage increases, the current also increases.
In the equation P = V^2/R, how does dissipated power relate to resistance?
power is directly proportional to resistance
the lesser the resistance, the lesser the power
power is inversely proportional to the resistance
the greater the power, the greater the resistance
