What do the following prefixes 1/1,000,000, 1000, 1,000,000, 1/1000
mean? Micro,Kilo,Mega,Milli
If you know the wattage and voltage, Divide the wattage by the voltage
how do you determine the current?
If you know the voltage and current Multiply voltage times current
how do you determine the wattage?
, If a circuit is supplied with 100 volts .5 amps
and the total resistance of the circuit
is 200 ohms, how much current will
the circuit draw?
If a piece of equipment is supplied 4160 Watts
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 one hot line? None
What happens to current in a parallel It divides across resistances
circuit?
what happens to voltage across the stays the same
loads in a parallel circuit?
what happens to the voltage across it divides across the resistances
the loads in a series circuit?
what happens to the current in a It stays the same everywhere
series circuit?
in a parallel circuit the total resistance the smallest resistance
of the circuit will always be less than
what resistance?
how do you find the total resistance add the resistances together
of a series circuit?
