The resistor and capacitor helps you to adjust the time period (or frequency) of the timer.
(Usually astable multivibrator is used as a timer in electronic circuits)
More the resistance, less is the current flowing through it. If the current flowing through is it to charge the capacitor is less, then the capacitor charges slowly. The timer changes it's state when the capacitor charges to a specific voltage ( Usually 1/3Vcc or 2/3Vcc). As it is made to charge slowly due to the high resistance, the clock frequency decreases.
In the same way, to increase the frequency of the timer, the resistance value needs to be reduced.

What type of resistance would exist for electrical timers?
none the resistance is in the wire not the timer
What is timer advantage?
time interval most use the timer
What two components in a timer circuit influence the timing most?
R (resistance) and C (capacitance).
Why is a timer is used in an electrical circuit?
Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay). If you want one device to turn off before the timer controlled device then you would use an off delay timer. If you want one device to turn on before the timer controlled device then you would use an on delay timer. When the timer is energized this starts the timer circuit in the relay to time out.
How do you make a 30 second timer?
You can use the 555 timer to make a one minute solid state timer.
What is the use of timer in electronics?
A timer can be used to controlthe sequence of an event or process.Himanshu Joshih.joshi002@gmail.com
What is the use of timers?
The recording timer is used to measure time. Races for example will use a recording timer to track certain records.

How long does it take for a timer ball to max out?
A timer ball cant max out, however once you use a timer ball the number of turns that have took place will be reset
How do you turn on the on timer on a samsung smart tv?
To turn on the timer on a Samsung Smart TV use your remote to look under the tools menu. Click on timer and select your preferences.
What would happened if you wired a 240v ballast and a 120 v ballast into a heavy duty timer?
The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
How do I build a 30 second timer that resets?
Do a google search for: 555 timer circuit You will find hundreds of circuits you can use.
