This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Electricity flows through wires In what frequency?
Most common electrical devices are set to operate as 120/240 V.
60 cycles per second.
When current flows - the resulting work is energy. Current flow tends to heat whatever its moving through - which is a useful characteristic of an appliance.
Watt.
2. What is voltage or electromotive force?
Stands for alternating current and it is when electrons move in both directions.
Hertz - one cycle per second is equal to one hertz. Electricity is caused to flow through wires at a frequency of 60 cycles per second. This means electrons flow one direction - then in the reverse direction - repeating this cycle 60 times every seco
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
3. What does the positive-negative attraction relate too?
KW-H
Hertz - one cycle per second is equal to one hertz. Electricity is caused to flow through wires at a frequency of 60 cycles per second. This means electrons flow one direction - then in the reverse direction - repeating this cycle 60 times every seco
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
4. What does P = E x I stand for?
From an electricians - pov - electricity is the movement of electrons. Electrons are atomic particles found in every substance. An electron has one main characteristic which is a negative electrical charge.
When current flows - the resulting work is energy. Current flow tends to heat whatever its moving through - which is a useful characteristic of an appliance.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
