Law of electric states that:
ANSWER✔✔ Like charges repel, and opposites attract.
When testing a supply voltage, a maximum variation allowed is typically:
ANSWER✔✔ plus or minus five percent.
A Voltage Tester reads zero when there is:
ANSWER✔✔ no potential difference.
An Ammeter:
ANSWER✔✔ Is used to measure the quantity and intensity of electrons
flowing inside a wire, or through a load.
When will an ammeter have an indication/reading of zero?

the magnetic fields will cancel each other out.
Resistance:
ANSWER✔✔ refers to anything that offers opposition to the flow of
electrons.
A circuit without resistance to control the electron flow is considered:
ANSWER✔✔ shorted.
Reading a VOM (Volt-ohm-meter), the difference occurs across:
