Question

ideally, a diode can be represented by a
select one:
o a. a fuse
o b. a battery
o c. a switch
o d. a resistor

Explanation:

An ideal diode acts as a one - way valve for current. In forward bias, it allows current to flow (like a closed switch), and in reverse bias, it blocks current (like an open switch). A fuse is for over - current protection, a battery is a source of electrical energy, and a resistor opposes current flow in a more linear way compared to the binary (on/off) behavior of a diode. So, an ideal diode is best represented by a switch.

Answer:

C. a switch
