Describe the difference between a sourcing input and a sinking input?

An NPN or sinking output accepts voltage and sinks it to ground to complete the circuit. A PNP or sourcing output sources voltage and the external circuit sinks it to ground to complete the circuit. A sourcing circuit would be drawn as voltage->switch->load->ground. A sinking circuit would be drawn as Voltage->load->switch->ground. In these cases, the switch could be a transistor.

Sinking and sourcing capability of microcontroller?
Sinking and sourcing current refers to current going into and out of the MCU (respectively)
Is PNP sourcing or sinking?
PNP is sourcing. NPN is sinking. You generally connect NPN to ground and your PLC(or any load)input. With PNP you connect to V+ and to your PLC. Your PLC (load) should have the same ground or V+. Sourcing (PNP) provides a path to +24DC generally. Sinking (NPN) provides a path to 0V DC.
Would a relay be wired differently for a sourcing and sinking output module?
Yes. For sourcing output, the relay coil is wired to (common or ground) and the output terminal. For sinking output, the relay is wired to (voltage supply or hot) and the output terminal.
What is the Difference between the future value of annuity and sinking fund?
future value of an annuity is a reciprocal of a sinking fund
What is the difference between npn and pnp proximity sensors?
No worries. The important thing here is that this module is simply reading a voltage from the sensor with reference to the ground of that sensor. This means that this module is always going to be a sinking device, and will be always be sinking small amounts of current from that sensor. This means, that your sensor is going to be powered externally and we will simply be reading the output voltage from it. Here is a link to a knowledgebase article about sinking and sourcing current. I hope this helps to clarify.
What is the difference between floating and sinking objects and the density of the liquid they are in?
a boat floats
Difference between line driver and push pull circuit?
Line Driver A line driver is a sourcing output. When in the on state, a line driver will supply Vcc. In the off state, a line driver will float. Because of this, a sinking input is required for proper operation. Open Collector An open collector is a sinking output. In the off state, an open collector will supply a path to ground. When in the on state, an open collector will float. For proper operation, a sourcing input is required. Push-Pull A push-pull output is a combination of a line driver and an open collector. In the off state it will supply a path to ground and in the on state it will supply Vcc.
Did the war of 1812 effect titanics sinking?
I would say not, since there's a 100 year difference between the two events.
What term is used to describe the location where sinking of a plate occurs?
subduction zone
What is the difference between amortization and sinking fund?
sinking fund is the setting aside of money for instance by the government to a pool to reduce its budget deficit while amortisation is the paying off of debts over a period of time with a decreasing principal balances and interests
What was the difference between those that might of survied to those who didn't on the Titanic?
Over 2208 were on the Titanic just subtract that from the amount of people who were killed during her sinking.
What is the difference between the sky and the sea?
sky is where you can see yourself rising.and sea is where your thoughts sink. but sometimes sinking is worth the while as one can find a treasure.
