Electrical Circuits Experiments Review

Practice vocabulary flashcards based on procedures and components for Physics Experiment 18 and Experiment 19.

2-volt accumulator

A power source used in Experiments 18 and 19, which can be substituted with a pair of $1.5\,V$ dry cells.

Standard resistor labeled S

A specific component included in the apparatus for Experiment 18 alongside the ammeter and resistance box.

$$V_0$$

The voltmeter reading recorded in Experiment 18 when the key $k$ is closed before setting specific resistance values.

Potential difference ($V$)

The reading recorded on the voltmeter in Experiment 18 after setting the resistance $R$ and closing the key.

Resistance ($R$) values for Experiment 18

The specific values set in the resistance box listed as $IS$, $22$, $32$, $4$, $5$, and $6$.

$V'$ and $R''$

The specific variables plotted on the vertical and horizontal axes, respectively, for the graph in Experiment 18.

Intercept $e$

The value determined on the vertical axis of the graph in Experiment 18.

Length $xy$

The measurement of the resistance wire provided at the start of Experiment 19.

$I$ and $V$ (Experiment 19)

The current ($I$) and corresponding voltage drop ($V$) across the wire measured for various resistance values.

Resistance ($R$) values for Experiment 19

The sequence of resistance values used in Experiment 19, which are $0$, $5$, $10$, $20$, $40$, and $602$.

Slope

The value determined from the graph of $V$ (vertical axis) against $I$ (horizontal axis) in Experiment 19.
