Ohms Law For Contractors Exam

Ohms law can be thought of as the relationship between voltage, current, and resistance

Voltage is measured in Volts (V) and is represented by the letter V

Current is measured in Amperes (A) and is represented by the letter I

Resistance is measured in Ohms (Ω) and is represented by the letter R

Current (I) = Voltage (V) / Resistance (R)
Amperes (A) = Volts (V) / Ohms (Ω)
Voltage (V) = Current (I) x Resistance (R)
Volts (V) = Amperes (A) x Ohms (Ω)

Example 1:

What's the voltage needed to generate 20 Amperes of Current in 6 ohms of Resistance?
To solve, use the formula for voltage.
V = I x R
V = 20A x 6 Ω
V = 120V

Example 2:

What is the current generated by a voltage of 120V through a resistance of 30 ohms?
To solve, use the formula for current.
I = V/R
I = 120V/30 Ω
I = 4A

Example 3:

What's the Resistance present if a voltage of 120V generates 15 Amperes of current?
To solve, use the formula for resistance.
R = V/I
R = 120V/15A
R = 8 Ω

Parallel Circuits

A parallel circuit is one in which current can flow through several paths simultaneously.

”ParallelCircuit
circuit with 4 resistors

Notice that unlike a series circuit in this circuit current flows through resistors 1, 2, 3 and 4 simultaneously.
If you stopped the flow of current at any of those resistors, current would still flow through the others. See circuit this concept.

”Parallel_Circuit_Xout”
interruption of flow through a branch in a parallel circuit. Does NOT affect the other branches
”Parallel_Circuit_5_resistors”
”Parallel_Circuit_branch”

Parallel Circuit Rules and Formulas

Total Voltage is the same or the voltage on any resistor. The voltage on all resistors is the same.

Total Voltage = Voltage at resistor 1 = ...Voltage at Resistor n
Vt = V1 + V2 + ... Vn

Total Current is the sum of the individual currents on the different resistors.

Total Current = Current at resistor 1 + Current at resistor 2 + ... Current at Resistor n
It = I1 + I2 + ... In

Total Inverse Resistance is equal to the sum of the inverses of the individual resistances

Total Inverse Resistance = Inverse Resistance 1 + Inverse Resistance 2 + ... Inverse Resistance n

Example 1:

What's the total current and total Voltage for the circuit below?
”Parallel_circuits_121_ex1”
It = I1 + I2 + I3 + I4
It = 5A + 10A + 10A + 5A
It = 30A

Since Voltage is the same everywhere in a parallel circuit, the total voltage must be 60V.

Example 2:

What's the total resistance of the circuit below? There are two ways of solving this problem.
”Parallel_circuit_ex2131”
You can use the formula for the total resistance.
1/Rt = R1 + V2 + R2 + R3 + R4
1/Rt = 1/30 + 1/30 + 1/15 + 1/30

To add fractions, I must find a common denominator. In this case, it is 9. We know that because 60 is divisible by 4, 12, 30, and 4.
1/Rt = 1/30 + 1/30 + 2/30 + 1/30

Notice the third fraction becomes 2/30 instead by 1/30 in order for all fractions to have a common denominator.
1/Rt = 5/30

Now, divide both the numerator and the denominator by a number that will turn the numerator into a 1. Let's divide both numbers by 3.
1/Rt = 5 ÷ 5 / 30 ÷ 5 = 1/6
1/Rt = 1/6
Rt = 6

Another way of nothing this problem is by using the circuit totals and using ohm's law

First, we calculate the circuit's total current
It = 2A + 2A + 4A + 2A
It = 10A

Then, we calculate the circuit's total voltage. If we calculate the voltage at any resistance, that will be the total voltage. Let's do it on the first resistance.

V1 = I1 x R1
V1 = 2A x 30 Ω
V1 = 60V
Vt = V1 = ... Vn
Vt = 60V

Now that we know
RT = VT / IT
RT = 60V/10A
RT = 6 Ω
