What do the following 1/1,000,000, 1000, 1,000,000, 1/1000
prefixes mean?
Micro,Kilo,Mega,Milli
If you know the wattage Divide the wattage by the voltage
and voltage, how do you
determine the current?
If you know the voltage Multiply voltage times current
and current how do you
determine the wattage?
If a circuit is supplied with .5 amps
100 volts and the total
resistance of the circuit is
200 ohms, how much
current will the circuit
draw?
, If a piece of equipment is 4160 Watts
supplied 208 volts and the
amp meter clamped to the
hot line reads 20 amps,
what is the wattage of the
load?
How much voltage is in None
one hot line?
What happens to current It divides across resistances
in a parallel circuit?
what happens to voltage stays the same
across the loads in a
parallel circuit?
what happens to the it divides across the resistances
voltage across the loads
in a series circuit?
what happens to the It stays the same everywhere
current in a series circuit?
in a parallel circuit the the smallest resistance
total resistance of the
circuit will always be less
than what resistance?
how do you find the total add the resistances together
resistance of a series
circuit?
how do you find the total 1/RT = 1/R1 + 1/R2 + 1/R3 ...
resistance of a parallel
circuit?
If a circuit is wired parallel, 120 volts
and the supply voltage is
120 volts, each load must
be rated at what voltage?
