### Key Questions

The following key questions are answered in this module:

What are the five key electrical terms for understanding electrical theory?
The five key terms are voltage, current, resistance, reactance, and impedence.

What is Ohm's Law?
Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across those two points. In equation form, it's I = E/R. Rewriting to solve for voltage, E = IR, and to solve for resistance in ohms, R = E/I. E = voltage, units in volts, I = amperage, units in amps, R = resistance, units in ohms, P = power, units in watts

What is Watt's Law?
Watt's Law is similar to Ohm's Law, whereas Watt's Law states the relationship between Power in watts, current, and voltage. In its equation form, it's P = I x E. Using Ohm's Law to substitute the value of E, Watt's Law can also be written as P = I2R.

What is Kirchoff's Law?
Kirchhoff's Law includes Current Law and Voltage Law, and basically states that the algebraic sum of all currents entering and leaving a node on a circuit must be equal to zero (Current Law), and the algebraic sum of all voltages within a circuit loop must be equal to zero (Voltage Law)
