... This was a 33 W resistor connected to a 20 V supply. The current would be 20 V ÷ 33 W = 0.61 A The power would be 0.61 × 20 V = 12 watts. Plenty enough to fry a 1 watt resistor. It is important that we ensure that any current limiting resistors can dissipate the power through them. The above situati ...

... Static electricity is when (charges, circuits) accumulate on the (inside, surface) of an object which gains or loses (electrons, branches) which move more easily on a (conductor, insulator) than they do on a (conductor, insulator). A negatively charged object has (fewer, more) electrons than a neutr ...

... But after the reflection, the assembly of these 5 resistors looks exactly the same as before. Hence they are the same circuit. We see that the direction of the current through the middle resistor (I3) is flipped, so the only way to ensure that both circuit are equivalent is for I3=0 We could have a ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
