Circuits

Question 1

Current is considered the flow of + charge even though what ?

Answer 1

Only - charges are actually moving

Question 2

What are materials that offer little to no resistance & materials that offer high resistance called ?

Answer 2

Conductors & Insulators (respectively)

Question 3

The # that characterizes the intrinsic resistance to current flow in a material is called what ?

Answer 3

Resistivity (ohm-meter)

Question 4

Resistors in series can be treated as a single resistor w/ the sum of resistors of all individual resistors & is termed ?

Answer 4

Equivalent or Resultant resistance

Question 5

What is characterized by its ability to hold charge @ a particular voltage ?

Answer 5

Capacitors

Question 6

The ratio of the magnitude of the charge stored in 1 plate to the potential difference (voltage) across the capacitor is known as ?

Answer 6

Capacitance

Question 7

What is another way of saying insulation ?

Answer 7

Dielectric material (can never be less than 1)

Question 8

What are some different types of meters used in circuits, & what do they measure ?

Answer 8

Ammeters: measure current @ some point in the circuit

Voltmeter: measures voltage drop between 2 points in circuit

Ohmmeter: can measure current in active or inactive circuit (can use readings to calculate resistance)
