◉ What meter would you use to check resistance. Answer:
Multimeter
◉ Which piece of test equipment would you use to measure the
insulation resistance of your conductor. Answer: Megohmmeter
◉ Which piece of equipment would you use to certify your conflict
monitor's ?. Answer: A MMU/CMU Tester
◉ Which piece of test equipment is commonly used to measure
voltage, resistance, and current?. Answer: Multimeter
,◉ Arc Flash. Answer: An arc Flash is an electrical explosion with a
tremendous
amount of pressure and heat. • Everything turns into molten
metal upwards of 35,000 degrees

◉ Ohms Law. Answer: E = I x R
E = Voltage (volts)
I = current (amps)
R = resistance (Ohms)
◉ Power formula. Answer: P = I x E
P = Power (watts)
I = current (amps)
E= voltage (volts)
◉ Electric current types. Answer: DC = direct current - electrons
flow in one direction
AC = alternating current - electrons switch directions
