Definitions
The unit of measurement used in current
Amperes (Amp's)
A circuit that has two or more paths for current to flow through. Voltage is the same across each component.
Parallel Circuit
If a circuit has a current of 72 Amps that runs through a resistor of 21 Ohms what is the Voltage in this circuit?
1512 Volts
The equation for finding Volts
V= IXR
This allows current to flow through it
A conductor
The unit of measurement used in Voltage
Volts
A complete circuit that allows electricity to flow through.
Closed Circuit
If a circuit has 23V running through a resistor of 33 Ohms what is the current of that circuit (round to the nearest tenth)
0.70A
The equation for finding current
I= V/R
These do not allow current to flow out of a conductor
A Insulator
Resistance force against electrons passing through a conductor or circuit
Ohms
A circuit is one in which all circuit elements are arranged in a single path
Series Circuit
3 Ohms
The equation for finding Resistance
R=V/I
The flow of electrons from atom to atom through a conductor.
Current
The unit of measurement used to show power over a period of time
Kilowatt hours
A circuit in which the continuity is broken due to which the electric current can not flow
Open Circuit
If my oven uses 1700 Watts and I use it for 2.7 hours a day. What is my total energy consumption (kWh) for a week?
32.13 kWh
What is the equation for finding the power of current
W=VXA
This states how current actually moves from negative to positive
Actual Current
Electric current is proportional to voltage and inversely proportional to resistance
Ohms Law
An electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.
Short Circuit
If my garage has 7 lights in it and each light uses 50 Watts and I run the lights for 4.8 hours a day while working. What is my total energy consumption (kWh) per month?
47.04 kWh
What is the equation for finding Kilowatt Hours
Kwh= Energy X Time
This states that electrons move from positive to negative. conventional current is the current state used in all engineering
Conventional Current
