Chapter 3 Flashcards
when just two elements connect at a single
node, they are said to be in ______.
________ circuit elements carry
the same current
Series-connected circuit elements carry
the same current
All of the seven resistors can be replaced with an ____________
Combining resistors in series
In general, if k resistors are connected in series, the equivalent single
resistor has a resistance equal to the sum of the k resistances, or
When two elements connect at a single node pair, they are said to be in
________.
____________ circuit elements have the same voltage across
their terminals.
Combining resistors in parallel
voltage-divider circuit
A voltage divider is a simple circuit which turns a large voltage into a smaller one
Current-divider circuit
Current Divider circuits have two or more parallel branches for currents to flow through but the voltage is the same for all components in the parallel cicruit
Voltage division
Current division
An ________ is an instrument designed to measure current; it is placed
in series with the circuit element whose current is being measured.
An ammeter is an instrument designed to measure current; it is placed
in series with the circuit element whose current is being measured.
A ________ is an instrument designed to measure voltage; it is placed in parallel with the element whose voltage is being measured.
A voltmeter is an instrument designed to measure voltage; it is placed in parallel with the element whose voltage is being measured.
ideally an ammeter has an equivalent resistance of ________, functioning as a short circut
ideally a voltmeter has an equivalent resistance of ________, functioning as a open circut
Digital meters
Analog meters
The Wheatstone bridge circuit
The Wheatstone bridge circuit is used to precisely measure resistances of medium values, that is, in the range of 1Ω to 1MΩ
Potentiometer
Galanometer
