Question 27

Medium

An engineer designs an electrical control circuit as shown in the diagram below.

Electrical control circuit with a 24.0 V battery, a 5.0 ohm resistor, a 15.0 ohm heating element, and a switch S connected in parallel across the heating element.

The circuit consists of a constant $V24.0\text{ V}$ DC power supply connected in series with a $Ω5.0\ \Omega$ resistor and a $Ω15.0\ \Omega$ heating element. A bypass switch $S$ is wired in parallel across the heating element.

Calculate the current in the circuit when the switch $S$ is open.

[2]

State the potential difference across the $Ω5.0\ \Omega$ resistor when the switch $S$ is open.

[2]

The switch $S$ is now closed.

Describe and explain how the current through the $Ω5.0\ \Omega$ resistor changes.

[2]

Describe and explain how the potential difference across the $Ω5.0\ \Omega$ resistor changes.

[2]

State the potential difference across the heating element when the switch is closed.
