What are independent and dependent sources?
An independent source is a source that produce constant currents and voltage. Dependent sources are voltage sources that depend on a voltage somewhere else in the network.
Two voltage sources can be connected in parallel when they are equal in?
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
Why two voltage sources of different voltage rating cannot be connected in parallel what is the coresponding statement for current sources?
Yes of course.. u just need some connecting wires to connect them in parallel
What is a Thevenin's equivalent circuit consists of?
A Thevenin's equivalent circuit is a single voltage source in series with a single resistor. It is electrically the same as any combination of voltage sources, current sources, and resistors that, as a black box, has two terminals. The technique is useful in simplifying circuits, when analyzing them.
What is drift voltage?
A: Drift voltage is an an wanted voltage that wander off from what is expected. I sources for wandering could be thermal or a component drifting in value.
What are independent and dependent sources?
An independent source is a source that produce constant currents and voltage. Dependent sources are voltage sources that depend on a voltage somewhere else in the network.
What is the effects of more than one voltage source in a network?
Two voltage sources in series can either add up or cancel out depending on which way round they are orientated. If the two positive or the two negative terminals are connected together, the overall voltage is the subtraction of the two. If the positive terminal from one supply is connected to the negative terminal from another, the overall voltage is the sum of the two.
How you calculate the polarity of voltage source across the resistor when two voltage sources are connected?
A: by using thevenin theorem
Two external sources of finance available to a sole trader?
examples of external sources of finance.
Two voltage sources can be connected in parallel when they are equal in?
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
Why two voltage sources of different voltage rating cannot be connected in parallel what is the coresponding statement for current sources?
Yes of course.. u just need some connecting wires to connect them in parallel
What happened to DC voltage source which is in series with AC voltage source?
The two sources add together, imposing a DC bias to the AC source.
Why do two ideal voltage source of unequal voltage cannot be connected in parallel?
If two ideal sources of unequal voltage are connected in parallel the higher voltage will provide a majority of the current (a two percent difference in voltage would provide an additional 5% of the current) and (in the case of batteries) the larger would provide charging current, quickly draining it.
Why two voltage sources of different voltages cant be connected in parallel and what happened when you connect them?
The higher voltage source forces current backwards into the lower voltage source, which can damage it or even cause it to explode.
In what way can multiple sources be wired to provide the greatest amount of voltage?
When DC voltage sources are wired in series they become additive.
What was the total voltage across both voltage sources connected together for the first circuit?
Sadly, I was not in the lab at the time, and did not observe the experiment. (I guess that makes two of us, eh ?)
What law is used to find the polarity of resistor when two voltage source are connected?
Hi! Well, it depends what voltage is "pushing" harder on the resistor. If you are ONLY dealing with 2 voltage sources and a single resistor, then the voltage source with the higher potential (or voltage) will dictate what polarity the resistor is. Cheers!
