12 Questions
What form of energy does a motor convert electrical energy into?
Motion and heat
Which statement about the flow of electrons is correct?
Electrons have negative charge and will migrate towards the more positive charge area.
What is the relationship between resistance and conductance according to the text?
Resistance and conductance are inversely related, with conductance measured in Siemens.
How does the total resistance change when resistors are connected in series?
The total resistance increases, with the high value resistors being dominant.
How does the total resistance change when resistors are connected in parallel?
The total resistance decreases, with the low value resistors being dominant.
What is the relationship between voltage, resistance, and current according to Ohm's law?
Voltage, resistance, and current are all linearly related.
What is the relationship between voltage and potential energy?
Voltage is the potential energy per unit charge.
How can the magnitude of voltage or current be increased?
Both A and C are correct.
What is the primary function of a voltmeter?
To measure the potential difference between two points.
Which of the following is an example of an energy source?
A battery.
What is the purpose of an energy sink in a circuit?
To convert potential energy into another form.
What is the significance of voltage being a relative measurement?
Voltage can only be measured in relation to a reference point.
