Skill Sheet 8-A Ohm's Law

... so does the current (flow of charges). You also understand that if the resistance increases, the current flow decreases. A German physicist, Georg S. Ohm, developed this mathematical relationship, which is present in most circuits. This relationship is known as Ohm's law: Voltage (volts) Current (am ...

... • The bottom node of the load resistor is connected to the source reference, so there is a current path back to the 11V source • KVL dictates that the load resistor has 11V across it • The bottom diode is reverse biased, and thus confirmed to be “off” • Thus our assumed state is correct ...

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.
