The electrical launch controller has four cells in series with a light bulb with

resistance, a switch and a load that has low resistance $($draw it as a resistor$).$ A second

switch runs in parallel to the light bulb.

$3$ Complete the circuit diagram for the launch controller as described above.

$4$ The light bulb has a resistance of $5\mathrm{.}4$ and the igniter has a resistance of $0,6.$

What is the resistance of the circuit when the second switch is open? Draw arrows

on the diagram to show where the electrons are flowing when the second switch is

open but the first one is closed.

$5$ The potential difference of a regular dry cell is $1\mathrm{.}5V?$ What is the potential

difference of $4$ regular dry cells in series?

$6$ What will the current be when the second switch is open but the first is closed?

Use GRASP. Use the $R$ and $V$ from the previous two questions.

When the second suttrehts closed most of the electrons will take a different route.

Redraw the circuit diagram and use arrows to show where most of the electrons

will flow.

$.$ I. Q$$

What is the resistance of the path shown in the previous question?
