A voltage tester is a popular tool with electricians. A voltage tester determines if there is a current running through a wire and determines if the current needs grounding.

What's the first test that should be carried out when working on a excisting electrical system?
1: Identify sources of supply 2: Isolate 3:Secure isolation 4:Test the voltage tester 5:Test the equipment is dead 6:Test the voltage tester 7:Begins work
How do you check if light bulb base is good?
use a voltage tester to see if there is voltage at the base pin
What is the highest range of voltage that can be detected by a tester?
The highest voltage scale on a hand held multimeter is 5000 volts.
Why does your radiator fan relay voltage go from 14 volts unhooked from fan to 0 when it is hooked up?
Sounds like bad ground... When using a voltage tester it does not draw enough to pick up whether you have a bad ground or not.. Then when you put a load on the circuit that is greater than that of the tester, the fan will not work if the ground is bad...
How do you determine if the light switch has power?
You will need a voltage tester to determine this. Put the tester across the top screw on the switch to the ground wire in the switch junction box. If there is an indication of voltage you can assume that the problem is further down the circuit. If there is no indication of voltage on the top screw then test between the bottom screw on the switch to the ground wire. Sometimes the "hot" is on the bottom screw. If there is no voltage present at the switch you have to work your way upstream towards the distribution panel to see what is interrupting the voltage.
Which of the following instruments can detect the presence of a voltage but not the voltage level a. clamp type meter b. wattmeter c. multitester d. neon circuit tester?
D. Neon circuit tester. Page # 59 in your book.
Can a high voltage transformer be megged with a megger meter?
No. A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution transformer or power transformer. Instead, a high-voltage test set or 'pressure tester' (e.g. a 'HiPot' tester) must be used, as these produce far higher voltages.
What is used to check for line voltage sags?
just a digital voltage meter measure at the origin, and then at the end of line
What source is the clamp tester placed around to measure the magnetic field?
Voltage source
Can a meggar tester be use to measure voltage standing wave ratio in a feeder cable?
No
How do you test a lawn mower voltage regulator that is off of the mower?
with a kohler regulator tester
Why does my outdoor lamp not work even if the voltage tester says there is power?
There may be a blown fuse or blown bulb. Kind of hard to pin down an answer with such limited information. Sorry.
