Transforming a switch into a voltage source

In summary, the conversation revolves around a circuit with a 12uV voltage source and a step function representing a voltage source. The purpose of the step function is to act like a switch and replace the original switch in the circuit. It is noted that the step function has a coefficient of -t and opposes the other 12V supply until t=0 when it goes off. The conversation also touches upon the similarities between the original circuit and the circuit with the step function.

i can't understand upon what bais they made such a transition

?

What is that thing? A 12uV voltage source backwards? Or is it supposed to represent the final current through the inductor?

its some step function
which represents a voltage sorse
-t says its zero from t>0 and forward

Oh, so it's meant to replace the switch with a step function. Okay.

its acts like a switch
its a step function of -t

from t>0 and forward it goes to zero like a switch

but how they got its coefficient of the step function?

i can't see how its the same as the original circuit
??

It looks to me like it generates a 12V that is opposing the other 12V supply, up until t=0 when it goes off and let's the other 12V supply be the only supply in the circuit. for t<0 when the two 12V supplies oppose each other, there is no net voltage to drive a current around the circuit.

can you describe how its like the original circuit?
 
  • #8
how its opposing ??

its plus 12
not minus 12

ahh thanks :)
 

Related to Transforming a switch into a voltage source

1. How does a switch transform into a voltage source?

A switch can be transformed into a voltage source by connecting it to a power source, such as a battery or a power supply. When the switch is closed, it creates a closed circuit and allows current to flow, converting the electrical energy into a voltage source.

2. What is the purpose of transforming a switch into a voltage source?

Transforming a switch into a voltage source allows for greater control over the flow of electricity. By opening and closing the switch, you can turn the voltage source on and off, creating a simple on/off switch for electrical devices.

3. Can any type of switch be transformed into a voltage source?

Yes, any type of switch can be transformed into a voltage source as long as it is connected to a power source. However, different switches may have different capabilities, such as handling different levels of current or voltage.

4. How does a switch function as a voltage source?

When a switch is closed, it creates a closed circuit and allows current to flow from the power source, creating a voltage source. The voltage is measured between the positive and negative terminals of the power source, with the switch acting as a connection between the two.

5. Are there any limitations to using a switch as a voltage source?

Yes, there are limitations to using a switch as a voltage source. For example, the switch may have a maximum current or voltage rating, and exceeding these limits can cause damage to the switch or the connected circuit. Additionally, the switch may have a limited number of times it can be opened and closed before wearing out or malfunctioning.
