Question

the term bias means
select one:
o a. the ability of a diode to block voltage
b. the amount of current across a diode
o c. a dc voltage that is applied to control the operation of a device
d. the ratio of majority carriers to minority carriers

Explanation:

Bias in electronics refers to a direct - current (dc) voltage applied to a device (like a diode, transistor) to control its operation. For example, in a transistor, biasing sets the operating point (Q - point) which determines if the transistor is in cutoff, active, or saturation region. Option A is related to the reverse - bias characteristic (blocking voltage) but is too narrow. Option B is about current which is a result of proper biasing (in forward - bias for a diode) but not the definition of bias. Option D is about carrier concentrations which is not the definition of bias.

Answer:

C. a dc voltage that is applied to control the operation of a device
