Both emf and pd have the same unit. namely volt
Both have the same definition. It is the work performed in moving unit positive charge right from one point to the other against the electric field.
Both are got by the product of current and resistance.
But emf is the pd across of a cell or source when it is not in action. So emf is slightly greater than the pd in the circuit as there may be a little bit of internal resistance.

When did Alfred Hitchcock enter into public domain?
I don't think any of his stuff is pd. Search pd movies & anything pd is on archives site for free download.

Can you measure the pd across pn junction by a simple voltmeter?
Yes.
Why a spark is produced in the switch of a fan when it is switched off?
when inductive load is switched off then current decreases as a result emf induced in the inductor or as whole of the circuit. There is air between switch and circuit wire. Emf tends to jump from higher pd to lower pd so air become ionised and spark is prouced
What is potensional difference PD EMF or voltage measured in?
They are each measured in volts (V).
What is the difference between emf pd?
The terminology E.M.F is the voltage output of a power source e.g a transformer bank, generator. As relates to potential difference it's a linear electrical field strenght between 2 points. E.g the charged plates of a capacitor.
What are the distinction between PD 603 and RA 9344?
ra 9344 is start with r while pd 603 start letter p
Why is there a difference in the number of alleles for hemophilia and redgreen colorblindness between males and females?
There is a difference in the number of alleles for hemophilia and red-green colorblindness, because when a carrier of protanomaly has a child with a deuteranomalic man. Denoting the normal vision alleles by P and D and the anomalous by p and d, the carrier is PD pD and the man is Pd. The daughter is either PD Pd or pD Pd. Suppose she is pD Pd. Thanks...
A battery of emf 2V is connected to an external resistance which is equal to its internal resistance and then find potential difference across the external resistance?
As the source impedance is equal to load impedance, it is assumed that both the resistances are in series. This distributes the whole voltage equally between both the impedance. Hence the PD across external resistance will be 1V.
Can terminal potential difference be greater than the emf supplied?
All cells have internal resistance. When connected to a load, the resulting load current results in an internal voltage drop across the internal resistance. This voltage drop acts in the opposite sense to the cell's e.m.f., thus causing its terminal voltage to fall below that of the e.m.f. The greater the load current, the greater the difference between the terminal voltage and the e.m.f.

What is the difference between EMF and terminal PD?
An electromotive force is the potential differenceappearing across the terminals of a battery, generator, etc., when that device is not supplying any load. When the device is supplying a load current, the electromotive force is equal to the sum of the voltage drops around the complete circuit, including any internal voltage drop.A potential difference (also known as a 'voltage'), as the name implies, is the difference in potential between two points.
When was PD Ports created?
