Voltage source and terminal voltage can be related as
A. terminal voltage is higher than the source emf
B. terminal voltage is equal to the source emf
C. terminal voltage is always lower than source emf
D. terminal voltage cannot exceed source emf
Answer:A
Voltage source and terminal voltage can be related as
A. terminal voltage is higher than the source emf B. terminal voltage is equal to the source emf C. terminal voltage is always lower than source emf D. terminal voltage cannot exceed source emf
Explanation: A practical voltage source can be represented with a resistance in series with the source. Hence, there would be some voltage drop at the resistor and the terminal voltage is always lower than the source emf.
