Electricity and Penumatics

Question 1

What happens to the current in a Series Circuit?

Answer 1

Current always stays the same in a series circuit

Question 2

What does a AND gate sybol look like

Answer 2

Question 3

What does a OR Gate look like?

Answer 3

Question 4

What does a NOT gate look like?

Answer 4

Question 5

Name the three points on a transistor.

Answer 5

Emmitter ( Top output )

Collector ( Bottom output )

Base ( left input)

Question 6

State the function of a resivoir.

Answer 6

A resivior Will cause a delay as it will take a certian amount of time for the tank to fill.

Question 7

What Equation would be used to calculate the resistance in a parallel circuit where there is more than 2 resistors.

Answer 7

Question 8

What is the energy change in an electrical torch?

Answer 8

Electrical to light

Question 9

What is the energy change in a solar panel?

Answer 9

Light to Electricity

Question 10

What is the energy change in a Car engine to wheels.

Answer 10

Chemical to kinetic

Question 11

what is the equation for work done?

Answer 11

Work done = Force Applied x Distance Moved

Question 12

What is the pneumatic symbol for main air?

Answer 12

Question 13

What is the symbol for exaust air?

Answer 13

Question 14

Describe why this actuator has the name “ 3/2 push button actuated spring return vavle”, ensure you have expalined about every section of the name.

Answer 14

This valve gets it’s name as there are three ports and two possible states, the actuator is activated by a push button, the actuator is then automaticly closed by the spring hence “ spring return” valve.

Question 15

What does a solenoid actuator look like?

Answer 15

Question 16

Why would hydrolics be used over pneumatics?

Answer 16

Hydrolics can applie far more force than pneumatcis can and this can have much more uses. The reason for it being stronger is that liquide cannot be compressed.

Question 17

Why would pneumatics be used over hydrolics?

Answer 17

Penumatics is not as powerful as hydrolics although pneumatics is not as dangerous and is very clean. If there is a leakage then only air will be released ino the suroundings.

Question 18

What is the equation to firgure out the outstroke force for of a single acting cylinder?

Answer 18

Area = πr²

Force = Pressure x Area

Question 19

What is the equations that can be used to figure out the force of a double acting cylinder while instroking.

Answer 19

Area of clylinder = πr²

Total Area = area of cylinder - area of rod

Area Total

Force = Area x Pressure

Question 20

What is the symbol for a unidirectional flow control valve

Answer 20
