Question

The type of timer operated on an electronic resistive-capacitance circuit based on the time required to charge a capacitor is:

a. Mechanical timer
b. Electronic timer
c. Capacitor timer
d. Millisecond timer

Answer 1

The correct answer is b. Electronic timer, which uses an RC circuit to create timed intervals based on how long it takes a capacitor to charge through a resistor.

Step-by-step explanation:

The type of timer that operates on an electronic resistive-capacitance circuit based on the time required to charge a capacitor is b. Electronic timer. This kind of timer makes use of an RC (resistor-capacitor) circuit, where the charging and discharging of the capacitor through the resistor define the time intervals. In electronics, one of the most well-known examples is the 555 timer IC, which uses an RC circuit to control the timing of voltage pulses. The time taken for a capacitor to charge up to approximately 63.2% of the supply voltage is known as the RC time constant, a key concept in designing and understanding electronic timers.
