Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.

Difference between direct and indirect measurement in electrical measurements?
ur face
What you measure voltage into?
You measure voltage using a voltmeter which involves measuring the electrical potential difference between 2 points in an electrical circuit.
What is difference between feeder and grid?
In an electrical power transmission system: the grid is what the feeder feed into.
What is difference between electrical and electricity?
Electrical is an one type of energy ie flow of electrons... this flow of electrons constitutes the Electricity which we are using for our use

What is the difference between upstream and downstream in a pharmaceutical industry?

The difference between Upstream and Downstream in Health promotion?
Upstream deals with primary prevention while downstrem deals with secondary and tertiary prevention.
What is Differential between upstream and downstream inter-company transaction?
downstream from parent to subsidiary upstream from subsidiary to parent
Difference between upstream and downstream management?
Simply Upstream is the management of raw material, from logistics to storage and finally processing, and Downstream is the management of finished products from storage to outbound logistics, marketing and sales and finally customer service.
What is difference between upstream and downstream in relation to oxygen sensors on vehicles?
Upstream will be the closest to the engine, and are used to sense the air/fuel ratio and tell the computer how much fuel to inject. Downstream sensors are used to verify the upstream sensors and convertors are functioning correctly, so they are located after the convertors.
What is functional difference between upstream and downstream oxygen sensors?
From what I understand , the oxygen sensor ( s ) upstream of the catalytic converter is used in the control of the air / fuel ratio . The oxygen sensor downstream of the catalytic converter is called a catalyst monitor and monitors the efficiency of the catalytic converter
What is the upstream of a river?
The upstream of a river is its mouth, AKA, the opening to the ocean, and everything in between. Downstream is the source, AKA the "beginning", such as a lake, and everything in between.To put it simply:A RIVER:(Mouth)=--------------------------------------------------------------------------------0 (Lake) Downstream
What is the difference between upstream and downstream in a food industry?
In the food processing industry, upstream involves farming of raw material such as fruits, vegetables, livestock rearing, grain, etc.The downstream stage in the production process involves processing the materials collected during the upstream stage into a finished product. The downstream stage further includes the actual sale of that product to other businesses, governments or private individuals.
What is the difference between DSL and ADSL?
ADSL is simply a version or 'flavour' of DSL. The 'a' refers to asymmetric, meaning 'not the same'. Hence, ADSL usually has different downstream and upstream rates (e.g. 1536/256 is a common speed of ADSL available in Australia, where downstream the link speed is 1536kbps and upstream is 256kbps).
Is there a difference between the upstream and the downstream oxygen sensor as far as the part number?
It depends on the make and model of your car. Sometimes the wires of the downstream sensor need to be longer than the upstream sensor. This would mandate a different part number. Sometimes the upstream sensor is a "wideband" or "universal" type O2 sensor, as opposed to a "switching" type O2 sensor (which is always found in the downstream position). This would also mandate a different part number.
What is the difference between bank 1 bank 2 and sensor 1 sensor 2?
Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
What is the difference between bank 1 sensor 1 bank 1 sensor 2?
Sensor 1 would be before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
