Can i put my load into your voltage out?

[run-bandit]

"What is the output voltage of circuit (b) (shown at the top of the next column) if a load of resistance 4.4 kΩ is connected across the output terminals of the voltage divider?"

--------------------------------------------------------------------------
 
Doesn't this question imply that the voltage out is going to be replaced by the 4.4 killer ohm resistor?

Would we just find the current through that line and multiple by resistance to give the voltage out?

I don't see why we would even need to do that or even know that there is a load there. Can't we simply aplly to voltage divider formula?

1. Total up resistance (for series circuit)

2. Find current through series circuit (same at all points in series circuit)

3. Using Ohm's Law, find output voltage

Doesn't this question imply that the voltage out is going to be replaced by the 4.4 killer ohm resistor?

Kilo ohms

[Edmund]

Voltage out is the voltage drop across the second resistor.

For a series circuit,







- remember this

Therefore, the total resistance is 6.6 kilo ohms



Then to find voltage output,

Hope this explains better...

[Edmund]

A load is just a resistor (that adds resistance) such as a bulb...

So all it's asking is, now we've added a bulb, what is the voltage across this?

I -think- load is a counting word for electrical stuff like resistance.

a flock of birds, ten of them
a herd of elephants, fourteen of them
a load of resistance, 4.4 kΩ  


Don't know for sure.. I'm just guessing, cause I could be reasoning in Engrish

Anyway I read

a load of resistance 4.4 kΩ

as

the 4.4 kΩ resistor

[the.watchman]

A load is an object on a circuit (eg. a light bulb or a resistor etc.)

EDIT: to refine this definition, I'm going to add that it is an object CONNECTED TO THE OUTPUT TERMINAL on a circuit

[Edmund]

do load = R2?

Yes
