The difference between a dc load line and an ac load line is the source of the electricity. A dc load line is coming from a battery and an ac load line is through a direct electrical current.
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
No difference a load is a load however AC/DC defines the type of a load that is.
Both are giving the data about storage capacity of a battery. For Ex. 12V 7AH Battery will run 7 hours if you are driving the load of 1Amp continuously. But 12 12AH Battery will run 12 hours if you are driving the load of 1Amp continuously.
Both terminologies are the same. The commonly used terminology used for a motor is FLA which is short for full load amps.
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load
