Basic Electrical Circuits #3 - Manual Inputs

What does it mean when a circuit is closed?

• There is a complete path for current to flow from positive to negative terminal

• The circuit is broken and current cannot flow

• The switch is in the off position

• Electricity is not being used

What are the two main components of a manual switch?

• Battery and resistor

• Capacitor and inductor

• Operator and contacts

• Wire and bulb

What is the function of a switch in an electrical circuit?

• To decrease the resistance

• To measure the current flow

• To increase the voltage

• To control when power is supplied to an output device

What happens when a switch is open?

• Electricity is generated

• The circuit is closed and electricity flows

• The circuit is also open

• The resistance is minimized

What type of switch is open until acted upon by the operator?

• Automatically operated switch

• Manually operated switch

• Normally closed switch

• Normally open switch

Which switch is often used where visual confirmation of the switch's state is important?

• Selector switch

• Pushbutton switch

• Knife switch

• Toggle switch

What does a pushbutton switch consist of?

• A knob and contacts

• A slider and contacts

• A lever and contacts

• A pushbutton-type operator and one or more sets of contacts

What is unique about a selector switch compared to a pushbutton switch?

• You rotate a knob instead of pushing a button

• It is activated by a machine

• It uses a lever to operate

• It cannot return to its unoperated condition
